I deleted the v1 function and uploaded the v2 function, but I got the following error:
! functions: HTTP Error: 400, Validation failed for trigger projects/unicard-83f52/locations/us-central1/triggers/matchmaker-471173: The request was invalid: generic::invalid_argument: generic::not_found: pattern cannot match any databases in region us-central1

Only functions using Oncall were successfully uploaded, and only trigger functions failed to upload.
