teams-js authentication.authenticate() not replacing parameters

Question

This was working until about a week ago. In my Teams tab app, I am using the authentication.authenticate() to use an external oauth provider. My app calls authentication.authenticate() with a URL that has two replaceable parameters with
{oauthRedirectMethod} and {authId} that should get filled in by the API before being sent to my auth endpoint.  They aren't.  This was working and now it isn't.

Here is the doc on using the API:
https://learn.microsoft.com/en-us/microsoftteams/platform/tabs/how-to/authentication/auth-oauth-provider

Please advise.

Thanks,
Michael
