Workflow exception - could not load FunctionProvider class

[Ashley Kim]

While importing data in JIRA, I got the following error message. 

JIRA server - version 6.4 

Is it because there are missing add-ons? 

Any idea?

Thank you, all! 

I found a missing add-on while going through postfunction of workflow transitions! 

I could finally import the project !

[Asha Ganesh]

hi ,Can u please mention how u found the add-on 

or kindly suggest the addon

[Nic Brough -Adaptavist-]

They went over the post-functions in the workflow, which will usually tell you which (missing) class is being called.  Most add-ons give their classes distinct names which can tell you, or at least allow a web search for the name of the add-on

[Nic Brough -Adaptavist-]

Also, if you read further down the log, you *might* find a "caused by" entry with the class of the missing add-on named.

[Vasiliy Zverev]

It seems that it really caused by some add-on. Could you provide list of postfunction on create transition?
