On `postActionURL`: method 'post' is not allowed when redirecting

trying to redirect to our subdomain (that hosts an application) from inside postActionURL (Auth0MFAWidget)

getting the following :

this is happening to a particular sub-domain only (example.DOMAINNAME.com)

Any hints as to what might be wrong here?

if the same request was a GET (instead of a POST), i wouldn’t be stuck :frowning:

but little/no documentation on the inner workings of Auth0MFAWidget and postActionURL means that no hint; the actual code I am using is postActionURL: "https://example.DOMAINNAME.com",
