Error: Missing Data

[Christopher Vanderzee]

Some of my students are getting this error when trying to train.  The work around I found is downloading the data, recreating the project and reuploading the same data.  Any idea how to fix/avoid this?

Thanks,

Sorry about that!

The checks that would've led to that error are:

- checking that any training data was present (ref)

- checking the metadata about the project (ref)

- checking the training examples (ref)

One of those checks must've failed. 

The ideal, perfect, would-make-it-trivially-easy-for-me-to-diagnose-and-fix-the-problem next step would be if you could get me a copy of what your browser sent when you clicked the "Train new machine learning model" button. 

You can do this by:

1. Open Developer Tools in your browser. You might be able to do this by pressing F12 or Ctrl+Shift+I (or maybe Cmd+Option+I if you're a Mac user). For more help on this step, please see https://balsamiq.com/support/faqs/browser-console/ 

2. In the view that opens, click the "Network" tab

3. Start recording - the confirmation that this is running is typically a small red button near the top - if you see a grey/black button that says "Start recording" or "Record network log", press it until you see the red icon)

4. Click the "Train new machine learning model" button

5. In the list of network requests look for the one that ends with "localnumbersprojects"

6. Click on it

7. Find the "Payload" or "Request" (the name depends on what type of browser you're using)

8. Please copy all of it and send it to me

You might also see on that "Network" tab an option to download all the network requests. It'll say something like "Save as HAR" or "Export HAR". That file (if you export it after you've clicked the "Train new machine learning model" button) would have the payload I need too. 

I realise that is a bit of a pain for me to ask for, but would you mind doing that, please? 

Kind regards

No problem.  I'll get that for you next time the error pops up.
