Hi, I have upgraded my heat from wallaby to xena. When I am trying to create magnum cluster its giving below error in heat engine logs. Currently in whole stack, I have upgraded heat and magnum to latest release. Before upgrading heat from xena to wallaby, the stack deployment was successful. 2021-10-08 12:06:14.107 2064 DEBUG novaclient.v2.client [req-31d11ee8-fc47-4399-b424-97adabf31331 admin admin - - -] REQ: curl -g -i -X GET http://controller-khi04.rapid.pk:8774/v2.1/98687873a146418eaeeb54a01693669f -H "Accept: application/json" -H "User-Agent: python-novaclient" -H "X-Auth-Token: {SHA256}ef71182888b7ad3b8719ee8d48e37c6cd526e1f25f8395f733770917aead9b7b" -H "X-OpenStack-Nova-API-Version: 2.1" _http_log_request /usr/lib/python3/dist-packages/keystoneauth1/session.py:519 2021-10-08 12:06:14.121 2064 DEBUG novaclient.v2.client [req-31d11ee8-fc47-4399-b424-97adabf31331 admin admin -
