Github action wait for cloud build to complete

Question

I trigger cloud build from github action (GHA) using gcloud command

  - name: Start CB trigger
    run: |
      export CLOUDSDK_CORE_DISABLE_PROMPTS=1
      gcloud beta builds triggers run iaisudh983u4923 --branch=main

Cloud build gets triggered asynchronously and GHA moves on. I would like GHA to wait for cloud build to finish processing and then based on whether cloud build succeeded or failed - GHA should proceed accordingly.

When I run the same gcloud beta builds triggers command locally - I get the same behavior. Command executes successfully without waiting for cloud build to finish executing.

In following code we trigger cloud build from GHA and then wait for status to be anything other then "QUEUED" or "WORKING"

To allow GHA to view logs from cloud build - grant role roles/logging.viewer to gha service account. This works only if logs are stored in logging and not in cloud storage bucket in the CB trigger yaml file

options:
 logging: CLOUD_LOGGING_ONLY

GHA code:

  - name: Start CB trigger to deploy main branch to dev GAE
    run: |
      export CLOUDSDK_CORE_DISABLE_PROMPTS=1
      BUILD_ID=$(gcloud beta builds triggers run ${{ vars.DEPLOY_DJANGO_TRIGGER_ID_DEV_2 }} \
        --branch=$branch --quiet \
        --format="value(metadata.build.id)")
      
      echo "BUILD_ID = $BUILD_ID"
      gcloud beta builds log --stream "$BUILD_ID"
      BUILD_STATUS=$(gcloud builds describe $BUILD_ID --format="value(status)")
      echo "Build status = $BUILD_STATUS"
      
      if [ "$BUILD_STATUS" == "SUCCESS" ]; then
          exit 0
      else
          exit 1
      fi
