Hi all ok I'm not a .net developer I'm from a PHP, python background and I'm not sure what to do with this.

I have the following error when trying to load one of our sites. Please can someone help

thanks guys

Your code will call System.IO.Path.CheckInvalidPathChars, which in turn checks for the the following:

1. double quote (")

2. left angle bracket (<)

3. right angle bracket (>)

4. veritical bar (|)

and for control characters less than 32 decimal (space).

So Make sure your path doesn't contain them.

Edit: comment from Guy Lowe

my issue was my unescaped \ in c:\ making it c:\ fixed it

Nice Stacktrace, but the invalid path would be more helpful.

In my oponion, the path provided to OpenBay.Utils.XPathUtils.GetNodes(string, string) has some invalid arguments. Use System.IO.Path.CheckInvalidPathChars() to check which characters are invalid and maybe contained in the argument provided to the method above.

Please look at this link, I am using VS 2019: VS Test cases issue, NUnit
