error in keyStore when building the application

Hi, I have a problem when trying to sign an application with an existing certificate in the files, I get a message that the user “example” does not exist, but use the KeyStore Explorer tool and the same user “example” appears and everything normal, I need help.

message:

Make sure that you provided correct credentials in ‘credentials.json’ and the path provided under ‘keystorePath’ points to a valid keystore file.
