Having WSO2 Identity Server v5.4.0 and following the documentation from this link Configuring OAuth2-OpenID Connect Single-Sign-On, I am unable to set Callback Url using regexp= for multiple URLs, even setting the example from the documentation:
regexp=(https://myapp.com/callback|https://testapp:8000/callback)
I'm getting the error:
"Please enter valid URI for Callback URL":
NOTE: with single URL (like "https://myapp.com/callback" I have no problems.
