Error Running URL Testing - Angular 4

[JessyRiordan]

I am trying to test a web page, but I am getting an error.

When I run Page URL testing with Axe it returns an error:

When I try and example page like google everything works.

Please help.

EDIT: Tried other Angular web pages.....

1. Angular 1 - AATT works
2. Angular 2 - AATT fails
3. Angular 4 - AATT fails
