Trying to stand up a new Cloud project with a GitHub repo and a Cloud Build trigger that tries to perform a cloud build when the develop branch is pushed to. The build has two steps, one a gradle build appengineStage and a second that essentially does a gcloud app deploy. I'm running into an "Internal error" that doesn't have any details associated with it. I've tried some online suggestions to try to get through this, but nothing seems to be working.

What you expected to happen:

• I expected either the operation to succeed or to give me a detailed, actionable error message.

Steps to reproduce:

cloudbuild.yaml

steps:

    - name: gradle:8.5-jdk21
      entrypoint: gradle
      args: [ 'build', 'appengineStage' ]

    - name: "gcr.io/cloud-builders/gcloud"
      secretEnv: ['SPRING_DATA_MONGODB_URL']
      entrypoint: 'bash'
      args:
          - -c
          - |
              echo $'\n  SPRING_DATA_MONGODB_URL: '$$SPRING_DATA_MONGODB_URL >> build/staged-app/app.yaml
              gcloud config set app/cloud_build_timeout 1600
              gcloud app deploy build/staged-app/app.yaml --verbosity=debug

artifacts:
    objects:
        location: gs://build-results
        paths: ['build']

timeout: '1600s'

options:
    logging: CLOUD_LOGGING_ONLY

availableSecrets:
    secretManager:
        - versionName: projects/<PROJECT_NUM>/secrets/mongodb-connection-string/versions/latest
          env: SPRING_DATA_MONGODB_URL

app.yaml

runtime: java21
#service: backend

env_variables:
  STACKDRIVER_LOGGING_USE_PREFERRED_LOGGING_BUCKET: "true"

Other information (workarounds you have tried, documentation consulted, etc):

• Other, similar problems reported online that didn't have relevant solutions. Some talked about setting permissions, but the service accounts seemed to already have the right ones and there's no detailed message to indicate what the actual problem is.
• Tried asking Gemini, but it could only give general troubleshooting hints.

(Since this bug is initially public, the above information is redacted. I can give more details privately if necessary.)
