In this run, a playlist request is launched and returns 0 but seems to have failed (output is not known as it ws successful) and produced no ZIM.

Was a recipe issue: ZIM filename was set without a .zim suffix so ZIM file was properly created but never uploaded by zimfarm worker.

Two things we can do at zimfarm level:

• make the UI fail on missing suffix for this field. We already do it somewhere else but each offliner has its own definition. https://github.com/openzim/zimfarm/issues/724
• Mark the task as failed if no ZIM file was produced (or uploaded, as already suggested) https://github.com/openzim/zimfarm/issues/723
