Error sending message to https://----mediator-url---- Cannot read property 'prototype' of undefined

[abhirams-tgrid]

I am trying to run the following code to initialize a Credo / Aries Framework Javascript agent in React Native iOS (Simulator as well as iPhone Device) environment in an Expo ^50 version :

import {
  Agent,
  ConnectionEventTypes,
  ConnectionsModule,
  ConsoleLogger,
  DidExchangeState,
  LogLevel,
  MediationRecipientModule,
  MediatorPickupStrategy,
  KeyDerivationMethod,
  HttpOutboundTransport,
  WsOutboundTransport,
  InitConfig,
} from "@credo-ts/core"
import { agentDependencies } from "@credo-ts/react-native"
import { AskarModule } from "@credo-ts/askar"
import { ariesAskar } from "@hyperledger/aries-askar-react-native"

const mediatorInvitationUrl = https://url...

const config: InitConfig = {
  label: "standalone-agent-11",
  walletConfig: {
    id: "standalone-agent-11",
    key: "00000000001000000000000000000011",
    keyDerivationMethod: KeyDerivationMethod.Argon2IMod,
  },
  logger: new ConsoleLogger(LogLevel.trace),
  // autoUpdateStorageOnStartup: true,
}

const agent = new Agent({
  config,
  modules: {
    askar: new AskarModule({ ariesAskar }),
    connections: new ConnectionsModule({ autoAcceptConnections: true }),
    mediationRecipient: new MediationRecipientModule({
      mediatorInvitationUrl,
      mediatorPickupStrategy: MediatorPickupStrategy.Implicit,
    }),
  },
  dependencies: agentDependencies,
})

agent.registerOutboundTransport(new WsOutboundTransport())
agent.registerOutboundTransport(new HttpOutboundTransport())

export const ScreenName = () => {

 useEffect(() => {
     agent
       .initialize()
       .then((_) => console.log("Agent initialized!"))
       .catch((err) => console.log("Agent not initialized:", err))
   }, [])

}

If i remove this snippet below, the code works perfectly fine and logs out Agent initialized! as expected:

  mediationRecipient: new MediationRecipientModule({
      mediatorInvitationUrl,
      mediatorPickupStrategy: MediatorPickupStrategy.Implicit,
    }),

But when I keep that snippet, I get the following error when I run yarn ios or yarn ios --device:

Note : I believe this has something to do with iOS/Xcode Configurations on network and other ends, because it seems to work on bare react native (Not Expo) apps but ONLY ON ANDROID VERSION.

I also posted this question on stack overflow but did not receive any help
