Error  Message :Additional information: The remote server returned an error: (500) Internal Server Error.

i am developing  an application in Asp.net mvc to integrate drobbox .

i am creating my web service to get access token from the dropbox by this following  method 

public string PostRequest(string postUrl, string contentType, string parameter, string access_token)
{
using (WebClient client = new WebClient())
{
client.Headers[HttpRequestHeader.ContentType] = contentType;
if (!string.IsNullOrEmpty(access_token))
client.Headers["Authorization"] = access_token;
string result = client.UploadString(postUrl, parameter);
return result;
}
}

here though  i pass all the parameters i get error .

it does not throw error while checking in Insomnia  client -- getting the accesstoken perfectly .

Help me to fix the issue..

Thanks & Regards,

I'll be happy to help with any issues you're having with the Dropbox API, but I'll need some more information. Please reply with:

- the name and version of the platform and SDK/library you are using.
- the steps to reproduce the issue, including the rest of the relevant code snippet(s).
- the full text of the error/any output. (Feel free to include screenshots if it helps.)

Thanks for your Reply ,

This is what my code used  to get access token .

I am using Visual Studio version 2015.

I get access token if  I pass same parameters in Insomnia , it throws  no issue in running Insomnia.

Regards and Thanks ,

Unfortunately this screenshot doesn't offer much more information, so I can't say what the issue is. For example, I don't see what the "UploadString" method is doing.

If you can share the 'X-Dropbox-Request-Id' response header value at least, I may be able to investigate based on that.
