Flowcode Not Working
Pernilla Gendron
In recent years, contactless technologies have become increasingly common in everyday life, for example, many businesses have started using QR codes, which are proving to be useful. QR codes are commonly used because they can be quickly scanned and accessed by almost all smartphone cameras.
Maybe your problem is not as technical as you might think! It is also possible that some external factors are preventing your QR code from working. Before exploring technical problems, make sure you do the following simple checks:
We frequently see this mistake, but the solution is easy: to make some concessions to the design. While QR codes with a black or dark background and a white or lighter foreground may look fantastic in some design scenarios, they cannot be scanned by all QR code readers. Many QR code scanner apps that scan your QR code expect its code to have a darker contrast to the background, so scanning QR codes with a white background color may not work for everyone.
Also be aware that there may be QR code scanner apps that can enable scan QR codes with inverted colors, but don't let this mislead you. But, if you say that I am determined to use inverted QR code colors in parallel with my great design scenarios, don't forget to do a QR code test by using different QR code scanner apps after doing it.
Contrast ratio and color selection matter! When selecting your colors against a white background ensure your QR code has enough contrast. Most QR code scanner apps need a darker contrast to the background, so it won't always function if you scan a QR code with a white or lighter foreground. If you have too much color contrast, it can be challenging for QR code scanners to scan the QR code in a light environment.
Also mixing similar light or dark colors prevents scanning the QR code properly. For example, light colors like lilac and yellow are not a good couple for scanning, therefore it is best and risk-free to use darker colors and white backgrounds.
What is this? There is something not clear. Is your QR code too blurry? It is very likely that you can not scan it. Give your QR codes the appropriate level of resolution so that they appear crisp on every display.
If you enlarge your image without checking the quality of the image, it can be difficult for QR code scanner apps to scan a blurry QR code. The safest and risk-free way, when you need to enlarge the picture, is to test whether the QR code can be scanned or not.
If you use a static QR code, you should first know that a static QR code stores data directly into the model, which means the more content you put in, the more pixels you have. Most scanners can't read a QR code with pixels.
If you have too much content, consider using a dynamic QR code, like a Flowcode, that doesn't store data directly instead stores a unique short URL by directing scanners to your embedded data. With dynamic QR codes, the amount of content does not affect the number of modules in your QR code and you don't have to struggle with the pixels.
QR codes are standardized for international usage. Those standardizations are size ratios to distances. The distance between the QR code reader and the QR code are measured at 10:1 for most current QR code readers. This means the QR code should be 10 inches away from the phone.
So, is your QR code too small? Just use the above ratio. The QR codes are sized according to the location and how you advertise. Namely, the size of the QR code will change according to where you place it. Just estimate how far you should be away from a QR code based on the QR code size. If you are too far out of the 10:1 ratio, you can have trouble scanning.
Are you sure that the link address is correct? Here are the problems you might face with your encoded data. If you type in a very long URL by hand instead of copying and pasting, you may have missed a character. Even if you did copy and paste, it is still possible to miss a character, leading your code to not work.
Another encoded data issue can be the typos in your text. When you're encoding your QR code to show a text instead of a URL, you should make sure that the message you give with QR code is correct. Otherwise, your QR code can be useless. For example, if your business card has a wrong or missing phone number, it will be useless for you.
Be mindful! The QR code generator you use can stop accessing your QR code without notifying you. The reason behind the problem is that most QR code generators set expirations on the codes or limit the number that they scan.
When you use a low-quality free QR code generator, your QR code can expire without your knowledge. The worst side of using low-quality free QR code generators, you can't know your QR code's expiration date. Also, you can have a limited number of scans for your QR code. Namely, when the limit is reached, users become unable to scan.
If your code is not working on the Android phone or IOS device, just try to download a third party QR code scanning app from the google play store or App Store. Also, you can try to use google lens for QR scanning.
Always do testing! Think about how you have printed thousands of business cards, leaflets, and billboards with a non-working QR code. Doesn't it sound scary? And a lot of unnecessary expenses... Not to mention the damage to your image/image of your company.

Forbes recently released their ranking of Best Startup Employers in the U.S. and Flowcode is on the list! Every year Forbes assesses over 2,600 workplaces of over 50 employees based on a combination of employer reputation and employee satisfaction and growth. Just a couple years, Flowcode has created an unparalleled community culture, and they weren't the first to recognize that.
"My belief in the product is what brought me to the team, and now it's the team that gets me excited to come to work every day! Our meetings are fun, the leadership team is transparent, and it's a blast working and playing hard with my peers."
"Flowcode has an amazing combination of seriously sharp and motivated people moving fast while maintaining a laid-back and flexible environment. The organization has a good relationship with tech debt: we accrue it where needed, but everyone is honest about where the skeletons lie, and the org is genuinely willing to commit resources to addressing it."
"My favorite thing about Flowcode is the people! Every day at the office brings an opportunity to learn and be challenged in the best way possible. No matter what team you're on, there is always someone who is ready and willing to support and guide you along the way. I've also had the opportunity to help hundreds of business owners, creatives, and individual contributors and it's been incredibly rewarding to guide them through their journey."
"My team! They are such a bright and supportive group that always has your back. I've learned valuable skills from every single one of them and the energy is contagious to keep accomplishing our goals."
"I absolutely love the high-energy, collaborative environment that Flowcode fosters. Everyone's deeply knowledgeable, and always willing to provide feedback, troubleshoot, or help in any way! We also constantly have the privilege of learning from some of the most successful business leaders, such as Tim Armstrong (our CEO, and previously the CEO at AOL), Jim Norton (our CRO, and previously the Chief Business Officer at Cond Nast), Kathleen McCormack (our CFO, and previously the CFO at BLADE), and so many others, including executives at other well-known companies.
Flowcode's open seating SoHo garage-turned-office is always buzzing with energy. Our office is a highly collaborative space stocked with an endless supply of coffee, snacks, and bagels that keep the team fueled. On any given day, you'll find people tossing a ball while brainstorming, clients bringing in treats, or the garage door open to the public. We're constantly hosting events -- come say hi!
As a remote-friendly workplace, Flowcode has two offsites each year to bring our full team together.

Flowcode has weekly routines that promote growth and build our community. Company wide meetings feature "PHD Classes" by our CEO Tim Armstrong on business case study lessons and professional development. Our Friday all-hands meetings are filled with shoutouts to celebrate team members constantly, and always end in laughter for our in-house memes section. On top of that, frequent group happy hours and an endless supply of Slack jokes are all part of the deal here.
In my first attempt I just used the same organization as my Prefect 1 code but just updated the relevant syntax. In a simplified version of my attempt, I have a repo where prefect is one directory in the root and under it I have:
When I run this main.py I see that the deployment is shown in the Prefect cloud UI. Then I start my agent (after setting AWS env) on my local machine and in the same repo root where I have access to prefect directory.
I see, so does that mean I need to have my Block defined with the AWS credentials? I thought since my agent is running in an environment that knows the credentials, it just needs to know the path from the block, and not the credentials.
By default, we use a temporary directory for each run which disappears after the run. If you want to check what actually gets pulled down from S3 you can set an explicit Process infrastructure with a working directory (docs):
Founded by former AOL CEO and Google exec Tim Armstrong, Flowcode saw success in the entertainment and media verticals. The company specializes in QR codes, using that format as a gateway for brand-to-consumer engagement. Through some earlier experiences working with the likes of ESPN and Turner Sports, Flowcode recognized that the sports viewer is far more interactive than the casual TV watcher.
