How to inform an object custom field with the API REST

[Diego Manríquez]

Hello everyone,

I'm trying to create an issue using the JIRA API REST. In this particular JIRA, there's a field that is mandatory in order to create the issue but it has a strange format. When I perform a GET this is what I retreived:

"customfield_XXXX": [ "{KEY}" ]

But when I try to update this customfield I need this format:

"customfield_xxxx": [ { "key": "{KEY}" } ]

But for some reason when I try to create an issue with this customfield, this error shows up:

"errorMessages": [],

"errors": { "customfield_xxxx": "{Name of the customfield} is mandatory." }

Is like it doesn't recognize the value. Can somebody take a look please?

Hi @Diego Manríquez Can you share exactly what your POST body looks like? What type of custom field are you trying to update? (e.g. single line custom field, multi-select list, etc.)
