Set reporter field based on customfield

[Davor Fisher]

Hello

We have a use case where we are migrating to JIRA Cloud and we use ServiceRocket SF and JIRA connector and issues created and pushed from salesforce all have reporter as the Salesforce and JIRA connector user. In our on-prem version of JIRA those are set as the person that is assigned the case in Salesforce. This is unfortunately not an option on cloud version of the app.

What I am trying to do is create a text field in JIRA that will be pushed from Salesforce to JIRA and it will map the values of User with Firstname Lastname.

I am hoping to then somehow figure out a way to update the reporter field and set it based on the custom field value of firstname lastname

JIRA field:

Salesforce Report: single line text field that would be ex. Davor Fisher

Reporter field: Set based on the above mapping.
