Currently, the Fabric Data Factory Invoke Pipeline task uses the user's credentials who saved the pipeline to then authenticate to the Azure Data Factory to execute the ADF pipeline. When that user's password is modified, the token expires and the Fabric Data Factory pipeline must be modified and saved for the Invoke Pipeline tasks to begin working again.
I would like to suggest that there be an option in the Invoke Pipeline Task to use the Fabric Workspace Identity, or specify a Service Principal for authentication to ADF.
Without this change, production Data Factory Pipelines will fail to execute after the owner changes their password.
