A convenience decorator was implemented in the API to improve the typing in the Task update endpoint called by the job runner. While this was extensively used and tested for usage in endpoints called by the Portal web UI, it contained an implicit conversion of JSON keys to snake_case. This was not picked up in the existing pre-deployment tests as we lacked sufficient variety in the Task data keys for test scenarios.

We apologize for the impact to affected customers. We are now introducing more robust tests around the Task data lifecycle and Task resubmissions.
