We need to be able to monitor details of JS errors that happen on our sites from 3rd party scripts and extensions.

We would like to request Tealium tag with the attribute crossorigin="true"  . We cannot do it  now because CORS policies.

Is possible to add header in Tealium tag response 

Access-Control-Allow-Origin: *

We see a lot of errors in our monitoring systems but we cannot see where these errors come from.

Please help
