API Post To Make Jira Ticket Not Working

[Raymond Liu]

So basically, when a customfield 11500, which is Source in our case, is added to the API Post request, we get a 400 error back. When that field is taken out, the ticket is made just fine.

I checked to make sure the value works(as in an available option), the syntax appears fine(it is exactly the same as the other fields, the custom field number is also correct, and the field is available for this issue type in the project.

customfield11500: {value: confirmedoption}

I also successfully made a Jira ticket with Source as a field manually.

Does anyone have any idea of what could be causing a 400 error?
