Sometimes it works, but when i got this error i have to wait few hours until this issue get out of my way.
Another user reported to me the same error with another data app.

To abroad this problem, i have to create a local workflow with same name as my PreProd WF, run the flow, test, and reset to upload in PreProd to overwrite my version, then i got a sketch to launch a new version working well.
