Missing Client Identifier - React Native firebase phone authentication Issue

Question

I am building an app with Expo React Native in managed workflow and using RN-Firebase for this. Now yesterday my app went into production and everything was fine.
And I am using development build of the app (without android and ios folders) for developing my application and today I am getting this error everytime i try to do phone authentication.

[Error: [auth/missing-client-identifier] This request is missing a valid app identifier, meaning that Play Integrity checks, and reCAPTCHA checks were unsuccessful. Please try again, or check the logcat for more details.]

Now my firebase has total of 4 SHA1, SHA256 keys. I have also added the App signing key generated by playconsole for my application.
But even in my development builds, i am getting this issue of missing client identifier.

Things i have checked:

Ensuring all SHA1 & SHA256 keys added to the firebase console.
Generating a new google-services.json file after generating keys.
Creating a new development build.
Enabled the PlayIntegrity API on CloudConsole

And another issue I've encountered in my production app was this . I was able to receive the OTP, but I was not able to sign in with that .

[error: [auth/session-expired] the sms code has expired. please re-send the verification code to try again.]

Any solutions would be appreciated! Thanks!!

I am still having this issue.
I managed to solve that issue by adding a very old SHA1 , SHA256 key which was stored on my pc.
It was working fine.
I generated a new production build of my application and uploaded on play console as Internal testing build. After that when i switched back to my development build and it started giving this issue again.

How i fixed earlier:
I used this command.

&"D:\Programs\Android Studio\jbr\bin\keytool" -list -v -alias androiddebugkey -keystore "$env:USERPROFILE.android\debug.keystore" -storepass android

You need to have the location of your keystore at the start.
Also Ensure all of the SHA1 and SHA256 keys are added with the updated google-services.json file.
