Code signing macOS fails

[AndrewSazonov]

The CI step of signing the code is now not working. Some of the issues are:

"Mac Developer ID Application: European Spallation Source Eric" 

error: The specified item could not be found in the keychain.
Error: Unable to upload your app for notarization.
Error: Notarization of 

MacOS applications using altool has been decommissioned. Please use notarytool. See:

Nevertheless, the step is marked as OK:
