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(cherry picked from commit 32dbd2f585ef1902478170f3a1153b1f71e81db3)\n(cherry picked from commit 8ee59604dcd9f770286f54e3a39c80f54413c358)\n(cherry picked from commit a90fe1951200ebd27fe74788c0a96c01104ac2cf)\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/e72c6a3a491b141f7e74b6a34692c1bddec40a1a"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/e72c6a3a491b141f7e74b6a34692c1bddec40a1a"}]},"branch":"refs/heads/stable/queens"}},"requirements":[],"submit_records":[],"submit_requirements":[]}
