Invariant Violation: View config getter callback for component `RTCVideoView` must be a function (received `undefined`)

Question

I am trying to use react-native-web-rtc in project. I have done all the setup for ios and i am getting this error

Invariant Violation: View config getter callback for component `RTCVideoView` must be a function (received `undefined`).

This error is located at:
    in RTCVideoView (at SomeView.react.tsx:96)
    in RCTView (at View.js:34)

This is similar to one with react-native-linear-gradient library issue

Invariant Violation: View config getter callback for component BVLinearGradient must be a function (received undefined)

This error is located at:
    in BVLinearGradient (at react-native-linear-gradient/index.ios.js:54)
    in LinearGradient (at SomeView.react.tsx:90) 

i have tried bunch of stuff like

• pod install
• npx pod-install
• react-native link react-native-linear-gradient
• clear watchman cache, clear pod cache

this issue still persist, i think library is not able to identify nativeModule,

Haven't tried this with android, this issue is when working with ios.
