I found the problem, the problem was a link infomed on the description field from the Sub Test Execution issue. So, when you use a Jira task link (e.g.: ABC-123) this error happens. I hope to help the Attlassian developer team with that information.

Same issue for me for the generation of the documentation of a test plan. 
5 tests cases was linked to this test plan.
In one of these 5 test cases, in its description, the number of another test case was mentionned (ABC-123). But only the text was displayed, not the Jira link. If I modify this reference ABC-123 by something else like ABC - 123, the generation of the documentation works.
No need to clone / move the workitems, the issue will still happen.
