jira-export crashes mid-job (System.ArgumentOutOfRangeException)

[The-Judge]

Describe the bug During jira-export execution, a System.ArgumentOutOfRangeException occurs. It first runs fine for the first projects but then crashes. In our config, we use a quite wide JQL to catch ALL issues: summary is not EMPTY ORDER BY createdDate ASC The export starts, successfully extract 6 projects and with the 7th, it suddenly crashes.

To Reproduce Steps to reproduce the behavior:

1. I can't provide; it has not happened with a JQL for 3 single projects of the same Jira in a row now, but it happens with the 4th config.

Expected behavior The application should not crash.

Following. Same issue here on Windows 10 using Jira Cloud. I've migrated around 10 project with no issue. This one started doing the same as @The-Judge.

The export says it exported all the items that I see in the JQL query (880) but there are only around 60 json files in the export folder.

Jira version : 1001.0.0-SNAPSHOT Jira type : Cloud System : Microsoft Windows 10.0.19042 jira-azuredevops-migrator-2.3.117 Agile template

Looks like this was resolved in #276 but never merged.

Just wanted to inform that for as long as this Bug is open, in the meantime I switched employers and aren't in need of a solution anymore. I'll unsubscribe, but will leave it open since others seem to have similar issues. Sad, that even after more than 4 months, there is not even a reply from a project member. Future users should take this into account when evaluating this software/agency behind it as their tool/partner.
