Misleading error message on RegEx

[SeanAdams]

If Alteryx encounters an error in a RegEx tool - it throws an error:

 RegEx (9) The field "Field1_Matched" is not contained in the record.

This is a somewhat confusing and misleading error message because the input data and the regex configuration have no "Field1" at all, so the error message does not assist with resolving the issue.

Could you please re-look at the error messaging on the RegExt tool to see if we can make RegEx errors easier to resolve by giving a self-descriptive error message?

Example below:

Here I was trying to tokenize by using the . to represent any character - however Alteryx is struggling with this.
