Identify Attachment Selector Field values in Java or REST API

[blindbg]

Hello

There is a custom field of type "Issue Attachment Selector Field" on form

It contains references to user selected attachments added to the issue. (not all attachments)

REST GET call to /rest/api/2/issue/MYISSUE-11 returns

...

"customfield_10100": [
"com.atlassian.jira.issue.attachment.Attachment@ffff9558",
"com.atlassian.jira.issue.attachment.Attachment@fcaac25e"
],

...

Same with Java API

@Grab(group='com.atlassian.jira', module='jira-rest-java-client-core', version='5.2.1')
, @Grab(group='com.atlassian.jira', module='jira-rest-java-client-api', version='5.2.1')

How can I match them to real attachment references , defined in the resultset?
... or convert String "Attachment@ffff9558" into Attachment object?

Thank you for any hint, gurus

@blindbgThis is not standard Jira field and is provided by plugin, 'Email This Issue'.

You need to check with them, because you are current getting Object reference in API and there is no way you can convert that to meaningful data.

Here is documentation of this field - https://metainf.atlassian.net/wiki/spaces/PLUG/pages/66093122/Custom+Fields
