Error: automatic_code_signing?

Suddenly I can’t build the app in Appflow.

Receives the following error message:

13: automatic_code_signing
[11:05:03 PM]: fastlane finished with errors
[!] Path is invalid
ERROR: Job failed: Process exited with: 1. Reason was: ()

Have searched everywhere, can’t find an answer to what this means and no explanation how to solve this.

The link on the Ionic Support page to the slack chat provides the message: Application error.

Someone who can help me and explain why I get the following error message and how to fix it?
