App is getting timeout when waiting response from mediator. Those are error logs for the mediator:

I would like to provide additional information regarding the issue mentioned by @francardoso93.

Currently, we are utilising our customised instance of the mediator service in conjunction with a React Native App that employs the Aries Framework JavaScript version 0.3.3.

This is how we configured the React Native Agent to work with the mediator:

const config: InitConfig = {
    logger: new ConsoleLogger(LogLevel.trace),
    label: `Agent1`,
    autoAcceptConnections: true,
    autoAcceptCredentials: AutoAcceptCredential.ContentApproved,
    indyLedgers: [
      {
        isProduction: false,
        id: 'bcovrin-test-net',
        indyNamespace: 'test',
        genesisTransactions,
      },
    ],
    walletConfig: {
      id: `some_id`,
      key: `some_id`,
    },
    mediatorConnectionsInvite: MEDIATOR_URL,
    mediatorPickupStrategy: MediatorPickupStrategy.Implicit,
    connectToIndyLedgersOnStartup: true,
  };

const agent = new Agent({config, dependencies: agentDependencies});

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

await agent.initialize().catch(e => console.error(e));

Note: MEDIATOR_URL is an environment variable with the mediator url.
