Invalid Package - SPFX Solution (solved)
Started receiving Valid App Package = No today while trying to update an app package in the catalog.
Looking at the unavailable apps view reveals the following error message:
Invalid SharePoint App package. Error: Unable to cast object of type 'Microsoft.SharePoint.ClientSideFramework.SPClientSideComponentMetadata' to type 'Microsoft.SharePoint.ClientSideComponent.SPClientSideComponentMetadata'.
Any suggestions?
I'm also unable to rollback the solution to any previously working version as I receive the same error there as well.
That was a bug that got out - we believe it should be working now. Can you let us know if you are still running into the issue?
