we are facing a critical issue, JIRA log
This exception is on "execute transition"/"change status" (example).
The first time I faced this issue it was self-fixed after upgrading the toolbox from 2.2.5 to 2.2.7.
Today we are facing the same issue in 2.2.7. After uninstalling toolbox JIRA went into "Service Temporarily Unavailable" mode. After restarting and installing 2.2.7 the problem was self-fixed.
Could you please investigate?
