Cancel Upload

Complete Upload MUTATION

Enqueue Job MUTATION
Queues a processing job on a live file. When the file already has an unfinished job of the same kind, returns that job instead of queueing a second one. Errors: KIND_UNKNOWN (no such kind), KIND_NOT_APPLICABLE (the kind does not accept this file type), NOT_FOUND (the file is gone, in the trash or not ready). Needs pipeline.trigger.
