Copying issues with external links results in 500 Internal Server Error

[Lyn]

When I try to copy a JIRA issue to another JIRA instance using JIRA to JIRA remote copy, I get a 500 internal server error (Java Nullpointer Exception) when the issue has a link pointing to an external site. The issue is still copied, however the links are not copied over to the new issue.

As soon as I remove the external link from the source issue and try to copy again, no error occurs.

J2J Issue Copy 6.0.0 on Jira Server 8.3.2 results with the same error if an issue has "Web Link" defined. Any solution to this? :(

[Doug]

We just experienced this exact same error. The issue was copied three times, but gave an error each time making the user think the copy did not work. Also, the external link was not copied over.

[Vasiliy Zverev]

Try to check that on JIRA instance you copy to you have requared link type

[Lyn]

Yes, the link type (web link) is also available on the jira instance we are copying to.

[Vasiliy Zverev]

This link to external site is a standard JIRA URL field or provided by some plugin?

[Doug]

For me it is a standard JIRA Web Link on JIRA 7.0.10.

[Vasiliy Zverev]

Before coping try to execute integrity check. Sometimes it helps.

[Doug]

Integrity Checker did not find anything on either JIRA instance. We run the Integrity Checker once per month.

Have you overcome the issue? We face the same.
