Interrupt is only supported when posting a comment

Error message

Interrupt is only supported when posting a comment

What it means

Solutions

  1. This is an authorization rule, not a bug: perform the action with an actor that satisfies the stated constraint (board user, the owning agent, or an in-scope resource).
  2. If access should be allowed, verify the actor's credentials/company scope and the resource's ownership before retrying.
