Summary

Large CSV exports can fail due to a timeout

Steps to Reproduce

1. Have a JQL query which yields a large number of results (900~1000 issues). This also occurs with complex JQL or searches with too many fields.
2. Try to export these results to a CSV file.

Expected Results

The file is generated successfully.

Actual Results

It took some time to get a response and eventually you get a 504 (Gateway timeout) error.

Notes

• The problem is intermittent.

Workaround

• Export Over 1000 Results to Excel from JIRA Cloud

• Split the CSV file into smaller batches, as exporting to the limit of 1000 issues may cause the timeout.

• Use REST API to get the results. JSON does not cause a timeout.
