General System.Exception is thrown as a parsing error

[elishapiiro]

During parsing an error is encountered:

System.Exception: Exception of type 'System.Exception' was thrown.

Unfortunately, I don't have access to the yaml document that caused the error, only to the logs.
The code that causes the error :

// yamlString is read from a file and not manipulated in any way.
using var streamReader = new StringReader(yamlString);
var yaml = new YamlStream();
yaml.Load(streamReader);

I believe that a more indicative exception should be thrown in this case.
