I have just finished setting up Salesforce Connector for Jira. I can successfully push data to a Salesforce case with no issues. But for some reason there is an issue with Salesforce updates syncing back to Jira.
When attempting to "Pull" data from Salesforce within the Jira ticket - I receive the below validation error:

Does anyone know why this may be happening? I have checked settings and permissions and nothing is jumping out responsible for this issue.
The SF admin has also configured the Visualforce pages to allow me to create Jira issues directly from salesforce. But again this is resulting in errors which look to be linked to the validation error.
Just for clarity - I am using the Connector for Salesforce & Jira by Service Rocket
Thanks
