The issue began on November 19 at 4:20 PM UTC and was resolved on November 19 at 6:24 PM UTC.

Cause:

We have identified that the source API is now returning a 400 GRAPHQL_VALIDATION_FAILED error when the allowMembersToInvite field is included in Organization endpoint requests, resulting in sync failures. This field previously worked without issues.
We are updating our linear connector to exclude this field, allowing affected connections to resume syncing.
