SOLVED: Error in calling Jira cloud REST api from scriptrunner rest endpoint

[Bruce Reed]

I've created a scriptrunner rest endpoint that will copy an issue from a JSD server to a Jira cloud instance. The post call to create the issue in Jira cloud is failing on a groovy.json.JsonException. If I use the exact same Json in a curl call to the cloud instance, it succeeds in creating the issue. Can anyone provide insight on what might be failing?

Here is the relevant endpoint code, using static strings to rule out a problem in the data read from the JSD issue. The log data follows. On the command line, the unprintable characters are all \u0000

 def http = new RESTClient(JIRA_API_URL);
 http.client.addRequestInterceptor(new HttpRequestInterceptor() {
  void process(HttpRequest httpRequest, HttpContext httpContext) {
  httpRequest.addHeader('Authorization', 'Basic 2UucmVlZEBncm91bmR0cnV0aC5jb206SDByc2VEcmF3bkJ1Z2d5')
 }
 })
 
 
 def jq = http.request(POST, JSON) {
    uri.path = '/rest/api/2/issue'
    body = [
       fields: [
         project: [
           key: "PLAC" 
          ],
         summary: "test summary",
         description: "test description",
         issuetype: [
           name: "Bug"
         ]
      ]
   ]
  response.success = { resp, reader ->
    result = reader.txt
  }
 
  response.failure = { resp, reader ->
    log.warn("Failed to query JIRA API: " + reader.text)
  }
}

Update: the call was fine. The error was my handling of the Json returned from the call.

@Bruce Reed what was the answer?

[Ron Horner]

Include the 'Accept': 'application/json' header in your POST request

restClient.post(
  path: "/rest/api/3/your/api/call",
  headers: [
    'Authorization': "Basic ${authString}", 
    'Accept': 'application/json' // <- include this to avoid the error
  ]
)

Hi Bruce,

Thanks for updating the post.  However in the future, it would help our system if you posted an answer to the question instead, and then accepted that answer.  That will automatically give the post the "SOLVED" prefix.

Thanks

Andy
