"errorMessages": "Unrecognized token 'filsdsrpinfed': When attempting to create issue

[Patrick Jakubowski]

I'm currently attempting to create a new issue, and either using curl or a python script I've been working on I get the following error (token depends on data it seems):

<Response [400]>

{"errorMessages":["Unrecognized token 'filsdsrpinfed': was expecting 'null', 'true', 'false' or NaN\n at [Source: org.apache.catalina.connector.CoyoteInputStream@12aa9c; line: 1, column: 27]"]}

The JSON I'm attempting to use is below, and as far as I can tell it's formatted correctly, and has all of the required fields for creating the issue.

payload = {
            "fields": {
                "project": {"key": "TST"},
                "summary": "Testing API creation",
                "description": "Creating of an issue using project keys and issue type names using the REST API",
                "issuetype": {"key": "Bug"},
                "reporter": {"type": "JenkinsJIRABot"},
                "customfield_10400": {"value":"Undefined"}
                }
            }

I'm using the user/pass validation if that makes a difference, can anyone help me resolve this problem? Thanks.

Figured it out, JSON whitespace was the culprit, was not properly removing it before sending.

What kind of JSON whitespace are you talking about? I get an identical kind of error, on a different API call and I am wondering what is the cause. The posted data is a valid JSON as I generated it with json.dump(). Any ideas?

I used json.dumps() on payload before passing it to request and it solved the issue
