GLTF file is not getting serve in GCP/app engine

Question

I'm using App engine and deploying react app. I'm trying to serve GTLF files but it's not able locate them. It's in public folder I think I'm specifying the path correctly from yaml file. Please correct me if I'm wrong.

It is working perfectly on localhost.

Is there anything else I'm missing?

runtime: nodejs20
env: standard
service: default
 
handlers:
- url: /static
static_dir: build/static

- url: /(.*\.(json|ico|js))$
static_files: build/\1
upload: build/.*\.(json|ico|js)$

- url: .*
static_files: build/index.html
upload: build/index.html

- url: /scene\.gltf
static_files: /scene.gltf
upload: /scene.gltf
mime_type: model/gltf+json
 
- url: /scene\.bin
static_files: /scene.bin
upload: /scene.bin
mime_type: application/octet-stream

I tried changing mime_type, tried using glb file but still App engine isn't able to locate that file.

Answer 1

Please make sure that the indentation is correct as per this example. Also, check if this format from this Github link would work.

Your code should look something like this:

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

If the suggestion I provided didn't work out, I would suggest filing this as a bug through this link so that Google Cloud engineers could take a look at it. This doesn't have a specific ETA on this but you can keep track of its progress once the ticket has been created.
