Google and facebook signed up cancelled, why??

[ShankarSubedi]

I am using mitm proxy to capture and analyze every request and response for study purposes. I am experimenting with McDonald's android app.
Basically I want to explore firebase APIs used for account creation, deletion and modification.

To bypass SSL pinning, I used android-unpinner which modifies Android APKs to inject Frida and HTTP Toolkit’s unpinning scripts as suggested in mitmproxy documentation.

I can capture all requests except when I try to sign up with google/facebook. It displays as google signin is cancelled or facebook signin cancelled.

Why is this happening and what is the solution for this?

ok when you regularly click sign up or sign in (without the proxy) where does it tke you?

because if it takes you to the browser, you may need to import the mitm cetificates in the browser as well.

or i advise you to already log in before hand regularly and then start the ssl bypass

I already installed mitm certificates in my browser, and I can redirect any request from browser.
When I click on sign in (without proxy), it isn't redirected to browser.
I dont know if it is handled by google play service or some other.

I need to check api related to account creation, so this sign in request can be skipped. But is there a way to bypass sign in cancelled by google? I dont know why this error occurs
