verifier._reset is not a function. (In 'verifier._reset()', 'verifier._reset' is undefined)

• Operating System version: Windows 20H2
• Browser version: CCleaner Browser 94.0.12470.84 (Official Build) (64-bit)
• Firebase SDK version: 9.2.0
• Firebase Product: AUTH
• Expo SDK: 43
• Node: 12.13.1

I'm implementing firebase phone auth but getting the below error:

verifier._reset is not a function. (In 'verifier._reset()', 'verifier._reset' is undefined) when getting token

  const auth = getAuth();
  const phoneProvider = new PhoneAuthProvider(auth);

  const id = await phoneProvider.verifyPhoneNumber(
    this.state.phoneNumber, //valid
    this.recaptchaVerifier.current //valid
  ); // throughs the message here
  
 //not reaching here
 console.log(id)

Although right after it, I'm receiving the OTP. But not getting token, required to complete the OTP verification.

STEPS TO REPRODUCE:

Installation:
expo install firebase

Code:

    const auth = getAuth();
    const phoneProvider = new PhoneAuthProvider(auth);    
    const id = await phoneProvider.verifyPhoneNumber(
     this.state.phoneNumber,
     this.recaptchaVerifier.current
 ); // throughs the message here

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

I think this issue should probably be raised with Expo. In v9, there is an expectation that the RecaptchaVerifier has an internal method called _reset(). As I understand it, Expo exports a RecaptchaVerifier that works with our libraries (the RecaptchaVerifier class that Firebase exports does not work in React Native). Please reach out to the Expo maintainers.
