Set-JiraIssue bails out with "Invoke-JiraMethod : Internal server error"

[MrMontesa]

Description

Hey JiraPS team, I have to admit that I'm not 100% sure if its me, my setup or something else miss behaving. But I'm testing for a few hours now, and cant get it to work. I'd like to create a ticket with a "request type" on a customfield. First I create the ticket and in a second call, I'm trying to set some fields including the customfield. Please find below, how I try to get this done.

Steps To Reproduce

$JiraFields = @{
                customfield_10200 = 'ithelp/d7b56ae0-1f76-4c64-8024-e314ea5309ac'
}
Set-JiraIssue -Issue $TicketId -Credential $JiraCred -Fields $JiraFields

I do receive the error:

Invoke-JiraMethod : Internal server error
At C:\Program Files\WindowsPowerShell\Modules\JiraPS\2.14.6\JiraPS.psm1:5505 char:21
+                     Invoke-JiraMethod @parameter
+                     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidResult: (:) [Invoke-JiraMethod], RuntimeException
    + FullyQualifiedErrorId : InvalidResponse.Status500,Invoke-JiraMethod

I verified that RequestType is customfield_10200 and checked the database for the correct content of that field using this howto: https://confluence.atlassian.com/jirakb/how-to-set-request-type-when-creating-an-issue-via-rest-api-using-rest-api-2-issue-endpoint-938041214.html

Expected behavior

The Ticket should be updated with the proper RequestType

Your Environment

Could you help me getting this command correctly to update the RequestType filed? Is there any additional info you might need? happy to provide. Thanks for your help and this awesome module.

Edit: adding the verbose output of Set-JiraIssue call. set-JiraIssue-error.txt

The verbose Set-JiraIssue call gave the following error:

DEBUG: [Test-ServerResponse] Investigating $InputObject.Headers['X-Seraph-LoginReason']
VERBOSE: [Invoke-JiraMethod] Status code: InternalServerError

Is that something I shall dig on my Jira Server?
