Variable Types Missing After Deployment to Another Workspace (Fabric Pipeline → ADF Pipeline + Varia

Hi mvdhoorn ,

Thank you for raising these questions in Microsoft Fabric Community.

Based on the current documentation and expected behavior of Fabric deployment pipelines, this is not described as a known limitation.

Parameter types are part of the pipeline definition and should be preserved when promoting pipelines across workspaces.

Variable Library based parameter types are also expected to remain intact after deployment. The promotion process should not remove or reset the type metadata of parameters used in an Invoke Pipeline activity.

There is no documented behavior indicating that parameter types are expected to be lost during promotion, and this is not a standard or intended outcome.

As a precaution, please ensure that the Variable Library exists in the target workspace and that the variables and their types match the source before deploying the pipeline.

If the issue continues after confirming this, please raise a Microsoft Support ticket for further investigation.

Please reach out for further assistance.
Thank you.
