So I've run into this issue with a web app I've made:
- it gets a file path as input
- if the file exists on a bucket, it uses a python client api to create a compute engine instance
- it passes the file path to the instance in the startup script
When I ran it locally, I created a python virtual environment and then ran the app. When I make the input on the web browser, the virtual machine is created by the api call. I assumed it used my personal account. I changed to the service account in the command line with this command 'gcloud config set account', it ran fine once more.
When I simply go to the source code directory deploy it as is, the application can create the virtual machine instances as well.
When I use Google cloud build and deploy to cloud run, it doesn't create the vm instance.
the web app itself is not throwing any errors, but when I check compute engine's logs, there is an error in the logs:

In theory, it is the same exact code that worked from my laptop and on app engine. I'm baffled why it only does this for cloud run.
App engines default service account was stripped of all its roles and given a custom role tailored to the web apps function.
The cloud run is using a different service account, but was given that exact same custom role.
Here is the method I use to call the api.

compute = googleapiclient.discovery.build('compute', 'v1')
