Componenet creatation failed with 404 in C# and REST

Hi there,

I am using REST API and C# to create a component under a project, but it fails with 404 error.

I used RESTClient, an add-on for firefox to verify the problem and found the response is 404 and "No project could be found with key xxxx". The project key indeed exists in JIRA.

Could someone kindly tell me any hints?

Thank you.

Ben,

Check if the user logging in to retrieve the REST call has permissions to browse the issues through the interface. This user must be in the Browse Project permission in the project's Permission Scheme.

Hi Pedro,

I am using a unique account which administers JIRA, so this problem should not be caused by permission limitation. How do you think? Any other clues?

Thank you.

can you share your code?

                                string data = null,

            string base64Credentials = GetEncodedCredentials();
            request.Headers.Add("Authorization", "Basic " + base64Credentials);

            }

            return result;
        }
public void CreateComponent()
        {
            string post_json = "{\"name\": \"Test Component\", \"description\": \"This is a test component from program\", \"leadUserName\": \"xxx\", \"asigneeType\": \"PROJECT_LEAD\", \"isAssigneeTypeValid\": false, \"project\": \"TEST\"}";

            try
            {
                string resp_json = RunQuery(JiraResource.component, null, post_json, "POST");
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }
}

I would like to create component under existing project with key "TEST", and it failed.
