Cause
The messages show Jira is looking for a claim myclaim (in this example), but couldn't find a user with the data from that claim (which is basically a field from the authentication response).
Solution
Configure the username mapping field in the SSO configuration to use the claim that matches the username in Jira. If in doubt, engage the Identity provider team.
