Create Issue via API returning "Option value is not valid" for Multi Select List custom field

[Adam Witek]

I'm trying to create an issue via the Rest v3 API and pulling my hair out.

Customfield _10930 is a Multi Select List.

What am I doing wrong?

{

 "fields": {

  "project": {

   "key": "PM"

},

  "summary": "This is a test issue",

  "issuetype": {

   "name": "Task"

},

  "customfield_10930": [

{

   "id": "12533"

}

]

}

}

If I do a "GET" on an  issue, I receive back:

"customfield_10930": [

{

"self": "https://virtualsystems.atlassian.net/rest/api/3/customFieldOption/12533",

"value": "dog",

"id": "12533"

}

It turns out I had an "test" Field Context setup and I couldn't see it because my list was so long. By scrolling to the bottom of the list it allowed me to delete the extra context.

Hi @Adam Witek 

You api post shoul look like this:

{
  "fields": {
    "project": { 
      "key": "REST"
     },
    "summary": "Issue created from REST API",
    "issuetype": {
      "id": "1"
     },
    "customfield_10300": {
      "value": "Mammal",
      "child": {
        "value": "Elephant"
      }
    }
  }
