Create issue returns: {"errorMessages":[],"errors":{"project":"project is required"}}


Here is my code:

string data = @"{ ""fields"": {
""key"": ""HELP""
""summary"": ""Test Ticket"",
""description"": ""Creating of an issue using project keys and issue type names using the REST API"",
""issuetype"": {
""name"": ""Ticket""
""assignee"": { ""name"": ""user"" }

var client = new RestClient();
client.BaseUrl = new Uri(Jira_systemID);
client.Authenticator = new HttpBasicAuthenticator(Jira_username, Jira_password);
var request = new RestRequest(Method.POST);
request.Resource = "rest/api/2/issue/";
request.AddHeader("Content-Type", "application/json");
request.AddHeader("Accept", "application/json");
request.AddParameter("application/json", data, ParameterType.RequestBody);
request.RequestFormat = DataFormat.Json;
Service1.trace(fn + "before client.Execute");
IRestResponse response = client.Execute(request);
HttpStatusCode statusCode = response.StatusCode;



Any ideas why i get : {"errorMessages":[],"errors":{"project":"project is required"}}


Many thanks

I just tried your json and it is valid. You have to find out what is really sent to Jira. I usually do it with Fiddler. You can proxy all requests over Fiddler and then you will be able to analize what is sent.

Or debug your program and see what is really sent to Jira.

Many thanks 

i works ok now with assignee=admin

but when i try with another user: ilan, i get an error

"errors":{"assignee":"User 'ilan' cannot be assigned issues."}}


i added "ilan" to "users" in my JIRA cloud account. 

Any ideas ?



There are can be several reasons:

1. ilan must be the user name not the display name. 

"assignee": {"name": "ilan" }

2. The user ilan can not be assigned to the issue. You can try to assign the user in Jira. If the user will be assigned then the user can be assigned

3. The user, by which your REST call authenticated in Jira, does not have permission to assign users in the project. Login to Jira by the same user and assign ilan to an issue upon creating.
