I am new to essential objects. So, I tried the sample for aspx.net to pdf and got this error. Why am I getting this? I am testing this on my localhost web server. Thanks

Thank you for your quick response. Like I said, I am new to this product. I really would like to use it if I can get it to work.

All I have on the page is a paragraph tag and button, nothing else.

Here is the stack trace.
