Twilio Voice iOS SDK: `callInvite is lacking` when accepting incoming name from CallKit or React Native

I am integrating Twilio Voice (v6.12.1) into my React Native app (utilizing Swift bridging for iOS) and have applied full VoIP, PushKit, and CallKit help for incoming calls.

✅ What works:

• Incoming calls set off the VoIP push and show the full-screen CallKit interface (or fallback UI).
• Decline Name works as anticipated.
• Name logs and occasions print appropriately.

❌ Drawback:

When I attempt to settle for the decision utilizing the CallKit Settle for button or React Native fallback UI, I constantly get:

❌ [TwilioVoiceModule] answerCall() callInvite is lacking

I additionally seen that the console logs for answerCall() are being printed thrice in a row, although the settle for button is barely pressed as soon as.

🔍 Observations:

• The callInvite is correctly obtained when the VoIP push arrives.
• However when answerCall() is triggered, callInvite turns into nil.
• This occurs in CallKit settle for, RN UI settle for, and even notification banner settle for.

📦 The way it’s arrange (summarized):

1. PushKit Registration – through PKPushRegistry in AppDelegate.swift

2. VoIP push dealing with – forwards payload to TwilioVoiceModule.handleIncomingPush()

3. CallKit integration – makes use of CXProviderDelegate to report and deal with settle for actions

4. JS Bridge – emits acceptCallAction to JS

5. React Native calls TwilioVoiceModule.answerCall(uuid, callSid)

6. In answerCall() methodology: self.callInvite is nil – so name can’t be accepted.

💡 Name Settle for Movement (iOS):

1. VoIP Push → TwilioVoiceModule.handleIncomingPush()
2. Twilio SDK creates callInvite
3. reportNewIncomingCall() triggers CallKit UI
4. On settle for: CXAnswerCallAction → emits occasion to JS
5. RN calls TwilioVoiceModule.answerCall(uuid, callSid)
6. Drawback: callInvite is already nil

❓ What I am making an attempt to grasp:

• Why is callInvite lacking when accepting the decision, and the way can I be certain answerCall() is triggered solely as soon as?

💬 Any assist could be appreciated.
