How to handle exceptions for invalid user name if assigned via jira rest API

[Shrinish]

Hello,

I am trying to set the assignee of the user as per the command:

PUT: https://localhost:8080/rest/api/2/issue/issue-key/assignee
Content-Type: application/json
Auth: Basic Auth

I am getting the following error: 

{ "errorMessages": [], "errors": { "assignee": "User 'sdxwwr' does not exist." }}

Could someone help me with the code to catch this exception

Note: The field where the user enters his name is a text field

Your rest call should look like this,

curl -D- -u username:password -X PUT -H "Content-Type: application/json" https://<JIRA_BASE_URL>/rest/api/2/issue/<ISSUE_KEY>/assignee -d "{\"name\":\"<ASSIGNEE_NAME>\"}"

Once you hit this API get response and parse it as JSON and it contains key 'errorMessages' or 'errors', it implies you had some error setting assignee. In your case above 'sdxwwr' is not user in your Jira.

If you want to know how to do it in any programming language let me know.

Hi DPK J,

Yes I would like to know how to do it in C#.

And what does this mean ?

-d "{\"name\":\"<ASSIGNEE_NAME>\"}"

This is JSON payload that you send to API as body just like you do when you call POST methods.

{
"name":"sdxwwr"
}

Yep that is how I do. Could you tell me some way to do it in C#

I mean the handling of exception:

{ "errorMessages": [], "errors": { "assignee": "User 'sdxwwr' does not exist." }}

I cannot provide you with C# sample as I am on Mac but here is Node.JS sample that can help you.

// This code sample uses the 'request' library:
// https://www.npmjs.com/package/request
var request = require('request');

var bodyData = `{
  "name": "<ASSIGNEE_NAME>"
}`;

var JIRA_BASE_URL  = "<YOUR_BASE_URL>";
var ISSUE_KEY = "<ISSUE_KEY_OR_ID>";

var options = {
   method: 'PUT',
   url: `${JIRA_BASE_URL}/rest/api/2/issue/${ISSUE_KEY}/assignee`,
   headers: {
      'Authorization': "BASE64_ENCODED<USERNAME>:<PASSWORD>",
      'Accept': 'application/json',
      'Content-Type': 'application/json'
   },
   body: bodyData
};

request(options, function (error, response, body) {
   if (error) throw new Error(error);
   console.log(
      'Response: ' + response.statusCode + ' ' + response.statusMessage
   );
   console.log(body);
});
