Intermittent 403 error returned via API retrieving worklogs - /rest/api/3/issue/{issueIdOrKey}/worklog

Summary

Intermittent 403 error returned via API retrieving worklogs - /rest/api/3/issue/

/worklog

Steps to Reproduce

1. Using OAuth 2.0 3LO authentication
2. Retrieve around 250 worklogs from a list of issues
3. Notice a failure rate of around 1/30

Expected Results

All worklogs are fetched without error

Actual Results

403 Intermittently returned

Notes

Right now, I'm trying to get all worklogs for a list of previously fetched issues. For that, I'm using `GET /rest/api/3/issue/{issueIdOrKey}

/worklog`. From what I can see in the API documentation, it requires `read:jira-work`.

The thing that I noticed is that the more worklogs I'm trying to fetch at one time, the more likely it is that the error will occur. For example, I have no errors with 30 worklogs, but with 250 the success/error ratio is about 1/30.

In the error I also got the information which specific url(

/worklog) caused the problem. I was trying to get only that one worklog in a separate call and it was just OK.

For me it looks like I'm trying to do too many requests at one time, but then, shouldn't the error be different than Forbidden 403?
