Post-function error blocks Create issue

[Max Andersen]

Hi All,

I have a Create Issue post-function on a status transition which is not 'firing' at all i.e. no issue is being created. My inclination is that it may be because of required fields however I cannot reconcile that.

The Create issue post-function looks like this (I am copying the three required fields from current issue - I would assume this is enough):

and the error log from JMWE looks like;

If anyone has any idea what is causing this lack of creation it would be most helpful and much appreciated

What happens if you create an identical issue manually in the UI, setting only the four fields you have named in the post-function?

[Max Andersen]

Works perfectly...

Also I have just tried to make the field Brand Manager, RtO, and Decription optional and suddently the tasks can be created again through the post-function and everything works. Is there a way to have the fields as requried and create issue's through post-functions? (would be ideal for newly created issue's of same type.) 

[Nic Brough -Adaptavist-]

Hmm, that suggests that the post-function is not giving the creation process the mandatory fields the new issue is demanding.  I can see that they are set up correctly, so I'm really not sure what might be going wrong, making me suspect it might be a bug.

I'd want to read the application log, but you're on Cloud, so we can't.  I think this needs to go to https://support.atlassian.com/contact as a support request to investigate further.

Thanks Nic - I will pass along to them.
