state, we\nexpect the current task state to be None and do not handle any\nUnexpectedTaskStateError exceptions that the database layer may throw\nat us. In those cases, we return an error 500 to the user, when in\nactuality an error 409 conflict would be more appropriate. This\npatch makes the API layer handle UnexpectedTaskStateError exceptions\nand return a 409 to the user.\n\nCloses-bug: 1850694\nChange-Id: Ie0b421cd5d3a5781c1dd09fab4ed013ece0f939d\n(cherry picked from commit a423d8b27785623550f401a200b68ca926c0a119)\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/32dbd2f585ef1902478170f3a1153b1f71e81db3"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/32dbd2f585ef1902478170f3a1153b1f71e81db3"}]},"branch":"refs/heads/stable/train"}},"requirements":[],"submit_records":[],"submit_requirements":[]}
