Go2Group CRM Plugin for JIRA Server : Error from CRM

[salvijus]

Hello,

I would like to synchronize attachments under Jira Task issue and Salesforce Task. When file is attached in Salesforce, plugin brings it to according Jira Task, but if file is attached in Jira, the plugin logs an sync error:

"Error from CRM: Attachment owner must be the same as the owner of the parent task or event"

Post in SF forum (https://success.salesforce.com/answers?id=9063A000000ZmerQAC) talks about possibly empty owner id...

Plugin's attachment options are configured as follows:

- Copying JIRA Attachments to CRM

-- Copy JIRA Attachments : All

-- Always Write to Case Attachments : No

- Copying CRM Attachments to JIRA

-- Copy CRM Attachments : All

-- Use matching JIRA users as creators : checked

-- Send Notifications : checked

How to force plugin to take attachment owner id from some field ?
