Creating a group calendar event fails with a 500 on 10 of 19 calls since 2026-10-11. The request bodies differ only in title, description and times, so the same request succeeds or fails at random.
We hit this in the test suite for the community API specification. Three workflows create an event in a group they created a second earlier, and nothing else touches the group in between:
CI runs with failures: 10-11 15:19, 10-12 14:07, 10-12 15:51, 10-12 16:37, 10-12 16:46
Request
