How to block transition when two user pickers are same

[Lily Wang]

Hi, 

I want to block the transition when the two user picker fields are same. But the jira expression seems always be wrong.

issue.customfield_12702[0].accountId != issue.assignee.accountId

It will always show this:

Message:

Evaluation failed: "issue.assignee.accountId" - Unrecognized property of `issue.assignee`: "accountId" ('accountId'). Type null does not have any properties

Can anyone help me ? 

Tks in advance.

Hi @Lily Wang ,

what is the type of custom field customfield_12702? Single or multi-user picker?

If it's a Multi-user picker, then the right expression is:

!issue.assignee || !issue.customfield_12702 || !issue.customfield_12702.some(it => it.accountId == issue.assignee.accountId)

If it's a Single-user picker, then the right expression is:

!issue.assignee || !issue.customfield_12702 || issue.customfield_12702.accountId != issue.assignee.accountId

Hi Lily,

Where are you trying to execute the code?
