Cloud Run setup failed due to static folder does not exist

[CloudMile-Robby]

When we are running this command:

$ gcloud run deploy csm-demo --source . --region us-central1
This command is equivalent to running gcloud builds submit --tag [IMAGE] . and gcloud run deploy csm-demo --image [IMAGE]

There is a step copy static folder in the Dockerfile, but we don't have this folder, so we got an error.

Error log:
