Hi,

I created two simple services based on nodejs and hello-world sample.

I am trying to explore dispatch.yaml

My dispatch.yaml.

dispatch:
  # Send all listing traffic to the listing frontend.
- url: "*/prolisting/*"
  service: prolisting
- url: "*/prolisting"
  service: prolisting
- url: "*/*"
  service: default

'prolisting' service app.yaml

runtime: nodejs14
service: prolisting

default service app.yaml

runtime: nodejs14

I have uploaded to bgsample.appspot.com.

The default works: bgsample.appspot.com

The prolisting also works: https://prolisting-dot-bgsample.uc.r.appspot.com

However, the following URL does not work

https://bgsample.appspot.com/prolisting

As per the dispatch.yaml, it should route to prolisting service, but gives the following error
Cannot GET /prolisting

my repo:
https://github.com/rajesh99/bgsample

Cheers,

Your app.js in the prolisting folder of the example repo does not have a handler for the /prolisting path. This is why express can't get the /prolisting [1].

Fix this by adding an additional handler for the path in app.js:

app.get('/prolisting', (req, res) => {
res.status(200).send('Hello, world prolisting!').end();
});

Note that when you dispatch with a path (i.e. /prolisting), the path is kept when calling the dispatched service. The dispatch rules do not remove the path.

I am further continuing to explore deploying a gatsby project to appengine

I created an appengine service called 'gatsby', and I want to serve in the following manner

https://bgsample.appspot.com/gatsby

app.yaml: gatsby-standard folder in the github: https://github.com/rajesh99/bgsample

runtime: nodejs14
service: gatsby

handlers:
- url: /gatbsy
  static_files: public/index.html
  upload: public/index.html
- url: /gatsby/
  static_files: public/index.html
  upload: public/index.html
- url: /gatsby/(.*)
  static_files: public/\1
  upload: public/(.*)

The main project: default-standard folder in the github: https://github.com/rajesh99/bgsample

dispatch.yaml

dispatch:
  # Send all listing traffic to the listing frontend.
- url: "*/prolisting/*"
  service: prolisting
- url: "*/prolisting"
  service: prolisting

- url: "*/gatsby/*"
  service: gatsby
- url: "*/gatsby"
  service: gatsby

There are two issues

1st issue:

https://bgsample.appspot.com/gatsby/ - this works

https://bgsample.appspot.com/gatsby - this does not work - why?

2nd issue:

https://bgsample.appspot.com/gatsby/ - Then click on 'A' link it works.

Now you do refresh, it does not work. Following displays on the browser

"Error: Not Found

The requested URL /gatsby/a/ was not found on this server."

I used the following reference to serve gatsby static files

https://github.com/gatsbyjs/gatsby/issues/22711

I have to say, I did not understand some parts of the app.yaml file.

Appreciate any help.

Cheers.

FYI,

I explored gatsby-express-plugin

It does not have the above two issues.

Please see bgsample.appspot.com/gatsby-express

See the corresponding github repository: https://github.com/rajesh99/bgsample

Hi ,

The following app.yaml file should work with Gatsby using the handlers like

handlers:

- url: /
static_files: public/index.html
upload: public/index.html

- url: /((.*\/)*[^\/]+\.[^\/]+)$
static_files: public/\1
upload: public/.*

- url: /(.*)$
static_files: public/\1/index.html
upload: public/.*/index.html

I also found this article[1] which might be helpful for your scenario. You can also check our documentation[2] for app.yaml elements which might be a great way to start resolving the error.

If you still have issues, I would suggest to please do open a case with us using [3] with all the information and we will look into it deeply.

Thanks,
