While trying to import from Trello the following Error is raised:
Unexpected failure occurred. Importer will stop immediately. Data may be in an unstable state
java.lang.RuntimeException: No valid issue type was found that can be used within the given project.
I've only found some related problem in JIRA Core which recommends to add some non-subtask issue type to the default issue type scheme as a workaround for JIRA Core.
Further investigation shows that the my JIRA Software Cloud "Default Issue Type Scheme" only has one Entry: Epic and cannot be modified.
What to dp?
