When I try deploying my Python code through Cloud Build to Google App Engine (GAE) I receive the following ERROR message:
ERROR: An app.yaml (or appengine-web.xml) file is required to deploy this directory as an App Engine application
ERROR: (gcloud.app.deploy) [/workspace] could not be identified as a valid source directory or file.
ERROR: build step 0 "gcr.io/google.com/cloudsdktool/cloud-sdk" failed: step exited with non-zero status
Can someone explain what might be causing this error?
