The first scenario returns an error-message that says "{:filename "data/scenarios/268/initial-b34a2559-cfc6-4963-b869-d12a7583bb8f.full-coverage.tif"}".

The second one "{:filename "data/.tif"}".

Locally, I have a similar failure when creating a scenario while its parent scenario state is pending. The error is different error-message: "{:context-id [:project 45]}".
