Post is failing with status code 500

[gmparker2000]

Great tool!  However, I cannot seem to get anything to work that uses a POST to my redmine (0.9.2).  Using GET to read tasks and such works perfectly.  Whenever I try to post time or create a new issue if fails with a 500 internal server error.  Anyone know what this might be?  Is there a particular log in redmine I could look at to try to find a reason?  I stepped through the source to try to pinpoint the problem but no luck.  The URL being used to hit the server works fine when I try directly in a browser.  Any help appreciated.

Hi

I can confirm, Im also getting same error - http://pastie.org/871154

If you comment out the ContentType setting in HttpHelper (line 251) you'll be able to commit the time. This doesn't fix the multi-part post for a new issue by the way.

The following source patch will solve the issue.

There is a same problem in Redmine 0.9.4. (exception string "HttpWebResponse)request.GetResponse();" in the HttpHelper.cs)
A new items couldn't be added.
I suppose the problems are in authorisation or cookies.  but I couldn't fix it.
Does anybody solved it?    /It would be great/

I am having the same issue when trying to add an issue. Itterating thru objects works GREAT!

The request to Redmine URL http://dev-yh:8080/redmine/projects/2/issues/new caused the following exception: The remote server returned an error: (500) Internal Server Error..
