Jira Cloud REST API - Errormessage

Suran Basharati

Hi, im sorry if im in the wrong section for asking this question, but im getting an errorcode: 400 when trying to POST a test issue, even tho my JSON is valid and is pretty similiar to the documentation.

Errormessage: 

{"errorMessages":["Can not instantiate value of type [simple type, class com.atlassian.jira.rest.v2.issue.IssueUpdateBean] from JSON String; no single-String constructor/factory method"]}

My Json: 

{
"fields": {
"project": {
"key": "SUP"
},
"summary": "Issue Title",
"description": {
"type": "doc",
"version": "1",
"content": [{
"type": "paragraph",
"content": [{
"text": "Some random generated text",
"type": "text"
}]
}]
},
"issuetype": {
"name": "story"
}
}
}

@Suran Basharati Welcome to the Atlassian Community!

This is pretty common error when you send in malformed JSON to API. But here I don't see any issue in your JSON (except for issue type name should be Story, names are case sensitive). I think your JSON to string conversion logic is not working fine.

For further diagnosis you can do two things,

• Try this CURL command, please do replace SITE_URL, EMAIL and API_KEY in command.

• curl --request POST \
    --url 'https://<SITE_URL>/rest/api/3/issue' \
    --user '<EMAIL>:<API_KEY>' \
    --header 'Accept: application/json' \
    --header 'Content-Type: application/json' \
    --data '{
      "fields": {
        "summary": "Testing create api",
        "issuetype": {
          "name": "Story"
        },
        "project": {
          "key": "SUP"
        },
        "description": {
          "type": "doc",
          "version": 1,
          "content": [
            {
              "type": "paragraph",
              "content": [
                {
                  "text": "Some random text",
                  "type": "text"
                }
              ]
            }
          ]
        }
      }
    }'

If case one (i.e. curl command) succeed then you are surely making mistake in send json data.
