I've had the same problem and tried the answer above with no luck. After a lot of trial and error I ended up with the app.yaml below. That one works for my setup using Google Cloud Build to deploy to Google App Engine directly.
As a bonus it also redirects HTTP requests to HTTPS, and skip files not usually needed.
I'm sure there might be more efficient ways to do this, but once I got it working I didn't dare change it any more.
app.yaml:
runtime: python27
api_version: 1
threadsafe: yes
handlers:
- url: /(.+\.js)
static_files: dist/project/\1
upload: dist/project/(.+\.js)
secure: always
redirect_http_response_code: 301

static_files: dist/project/\1

redirect_http_response_code: 301

skip_files:

- ^(.*/)?\..*$

I tried the above and it works for me but the only thing is on every refresh it get redirected from the home page. Any workaround for that or am I missing something here.
