I have a webapp with passkey based login but It doesn't work when I open the link to the webapp through telegram (since it opens in the telegram in-app browser)
Unable to process the registration options generated from the backend. 

Get the following error {"name":"NotAllowedError","code":"ERROR_PASSTHROUGH_SEE_CAUSE_PROPERTY"}

What is the issue and how can I fix this?

I am using the https://simplewebauthn.dev/ libraries on the frontend and backend for my app.

The app works fine when opened in a normal browser on mobile or desktop devices (chrome, safari, etc)

I assume that's an issue with the mini-browser.

Considering it says see cause property, the question is if there is one such property in the object that tossed the error.

in Telegram you can say to open sites with the normal browser both in general and for specific sites however you like.

Regards

Oh there is a type of webview that allows an app to be evil browser, yeah damn right webauthn doesn't work there.

Imo general use webviews should maybe use the system webview rather than an embedded one.
