Google Cloud Build show no logs

Question

I have a Google Cloud Trigger that triggers cloud build on Github push.

The problem is that the Cloud Build shows no logs. I followed this doc but can not find any logs on neither the Cloud Build log nor the Logs Explorer (see the image below)

This is my cloudbuild.yaml

steps:
# install dependencies
- name: node:16
  entrypoint: yarn
  args: []
# create .env file
- name: 'ubuntu'
  args: ['bash', './makeEnv.sh']
  env: 
    - 'GCP_SHOPIFY_STOREFRONT_ACCESS_TOKEN=$_GCP_SHOPIFY_STOREFRONT_ACCESS_TOKEN'
    - 'GCP_SHOPIFY_DOMAIN=$_GCP_SHOPIFY_DOMAIN'
# build code
- name: node:16
  entrypoint: yarn
  args: ["build"]
# deploy to gcp
- name: 'gcr.io/google.com/cloudsdktool/cloud-sdk'
  entrypoint: 'bash'
  args: ['-c', 'gcloud config set app/cloud_build_timeout 1600 && gcloud app deploy --promote']
timeout: "1600s"
options:
  logging: CLOUD_LOGGING_ONLY

The build failed but it actually create a subsequence App Engine build that successfully deploy a version to App Engine. But that version is not auto-promoted (see the image below)

I do not have all the details, so trying to help with all the above information mentioned.

As I can see you are using CLOUD_LOGGING_ONLY and not been able to see the log in the log explorer and considering you have all the permissions to access the logs.

I would suggest you to look into the service account that you are using for cloud build must at least have the role: role/logging.logWriter or permission:logging.logEntries.create permission if it is not the default cloud build SA project-number@cloudbuild.gserviceaccount.com.

Hope this helps :)
