Error message

Issue ${issue.identifier ?? issue.id} is linked to a project workspace but has no project id; refusing to launch ${input.adapterType} from fallback cwd.

What it means

Launch-safety guard in the heartbeat pre-launch workspace checks: the issue is linked to a project workspace but carries no projectId on the input, and the adapter is about to launch from the fallback cwd. Launching from the agent fallback directory would silently bypass the project workspace, so the run is refused instead.

Solutions

1. Link the issue to a project with a valid project id, or unset the project workspace link, then retry.
