We are getting this error intermittently from forms when calling the workflow web service /workflow being hosted by IIS

Since it is a 500 error, that means we need to look to the web service to find the error details, but the web service is different than the workflow product itself.

I can't seem to find where it's logs are in order to view the error. Tried looking under Event Viewer but there is only a WebClient sub directory.

How do we reach the actual error message so we can begin troubleshooting?

Inner exception: System.Net.WebException
Message: The remote server returned an error: (500) Internal Server Error.
