Summary

• After migration to the JIRA cloud from the server, none of the apps can be installed from Marketplace. 

• On every try an error shows up: We ran into a little trouble

Environment

JIRA  CLOUD 

Diagnosis

In backend logs, we came across the error message: 

 msg: Failed to create Connect user remotely: {"schemas":["urn:ietf:params:scim:api:messages:2.0:Error"],
"status":"404","detail":"No default group for Jira Service Management",
"errorType":"NoDefaultGroup","message":"No default group for Jira Service Management","data":"Jira Service Management"}

Cause

The root cause of the issue was the absence of "Default Access Group" for product JSM. None of the groups were marked as Default Access Group. 

Solution

Mark a group as Default Access group from the list of groups available under product access. If only admin groups are present create a new group and then add it in product access and mark default.
