Scriptrunner 'switch to a different user' fails

Question

On JIRA Software 7.2.2 (and Service Desk 3.2.2), Scriptrunner 4.3.7.

When trying the build in script - Switch to a different user, the script throws an exception:

java.lang.NullPointerException: Cannot invoke method getRemoteUserKey() on null object

Anybody that have seen this before?

We have just upgraded to the new JIRA and scriptrunner versions.

This has been fixed in 4.3.8 and has been released, or 4.1.3.18 for JIRA 6.

This is a bug in 4.3.7 unfortunately. Please see SRJIRA-2040.

We are looking at fixing this as soon as possible and putting out a new release.

For now you can downgrade to 4.3.6 if this is a problem for you.
