Jira API Add Worklog v2 and v3 have different requirements

Question

I've got a curl script that can add a worklog via the Jira API: curl -u : -H "Content-Type: application/json" -X POST "/rest/api/2/issue//worklog" -d "{\"comment\":\"Test\",\"started\":\"2020-02-19T09:00:00.000-0700\",\"timeSpent\":\"8h\"} However, using v3 of the API with everything else exactly the same always results in: {"errorMessages":["Invalid document format","Worklog must not be null."],"errors":{}} Not sure what's so different, especially considering the documentation here and here appear to be the same... Would somebody mind clarifying and/or updating the documentation for v3?

but the docs say "A comment about the worklog in Atlassian Document Format. Optional when creating or updating a worklog."

Urs Spycher · Answer

From v2 to v3, the format of 'comment ' changed from a simple string to the more complex Atlassian Document Format (as documented in the API spec).

I don't understand the reply from @Niko Tzioras. @Tomas Eychaner did you find out what the problem is?
