Input is not a service identifier.

Error message

Input is not a service identifier.

What it means

parseIdentifier accepts only existing identifier objects or constructors and throws 'Input is not a service identifier.' for anything else, normalizing all DI lookups to IdentifierValue and catching garbage keys early.

Solutions

1. Pass a service identifier created by the framework's identifier helpers, not a plain string or class.
2. Check the call site and replace the invalid input with the correct identifier export.
3. Verify the identifier import comes from the module that defines the service.
