I'm connecting to a Jira instance from ServiceNow using what's called the Jira Spoke. Basically it looks like it's using a REST endpoint to retrieve data about Jira issues. We update several fields within ServiceNow with data from Jira, except for 1 field. In this instance it's called Fix Version/s. I can not get any data from this field. I think it's some type of object array, but I'm not sure if the name is fixVersion, fixVersions or whatever. I can't see any metadata about the field, so I have no idea if it's a top level field in the retrieved JSON object, and apparently the object is to big for ServiceNow to display all the possible fields. Is there a standard hierarchy of fields somewhere, with field label/type information?
