structure plugin migration failed

[Rajamony, Mukund (ext) (DI SW PLM STS SDDEV MECH ARCH)]

Hi, I had a structure with a custom column formula as below on data center jira instance.

issueLinks.FILTER($.type ='xxx') .MAP(IF $.source = this: $.destination).assignee.displayName

With the cloud migration, this formula does not work. I looked at the migration help 

Comparision Between Formulas in Cloud and Data Center

It appears that there is no migration for "this".

Please suggest suitable workaround.

Hello @Rajamony, Mukund (ext) (DI SW PLM STS SDDEV MECH ARCH) 

The this function can be replaced by key.

But please note - the Assignee field values are not accessible by the issueLinks function at the moment. You can find the list of fields that can be extracted in our documentation.
We have plans to expand the list of available attributes in the future.

If you need more assistance with Structure, please reach out to us directly at our support portal.

Best regards,
