Using base64 encoded strings fails creating the secret

[AMecea]

tools version: 0.10.1

In the scheme.yaml

  dashboardOIDCClientID:
    type: string
    title: Auth0 Client ID
    x-google-marketplace:
      type: STRING
      string:
        generatedProperties:
          base64Encoded: dashboardOIDCClientIDEncoded

in the apptest/deployer/schema.yaml

properties:
  dashboardOIDCClientID:
    type: string
    title: Auth0 Client ID
    default: "test"
    x-google-marketplace:
      type: STRING
      string:
        generatedProperties:
          base64Encoded: dashboardOIDCClientIDEncoded

running mpdev verify
I'm getting:

Error from server (BadRequest): error when creating "/data/resources.yaml": Secret in version "v1" cannot be handled as a Secret: v1.Secret.Data: decode base64: illegal base64 data at input byte 1, error found in #10 byte of ...|dGVzdA=='","CLIENT_S|..., bigger context ...|apiVersion":"v1","data":{"CLIENT_ID":"b'dGVzdA=='","CLIENT_SECRET":"b'dGVzdA=='","ISSUER":"b'aHR0cHM|...

This is because the variable is replaced with b'<base64 encoded string>' instead of just the string, this is related to python3 byte string that is not decoded before serialization.
