So, I have the following piece of code in my React Native application:

const network = 'goerli' // use rinkeby testnet
const provider = new ethers.providers.AlchemyProvider(network, API_KEY)

I am calling the following method to fetch the current block number on the goerli testnet:

provider.getBlockNumber().then(
    result => console.log(result)
).catch(
    error => console.log(error)
)

I am getting the following error on my console:

[Error: missing response (requestBody="{"method":"eth_blockNumber","params":[],"id":48,"jsonrpc":"2.0"}", requestMethod="POST", serverError={"line":34814,"column":24,"sourceURL":"http://192.168.18.83:19000/node_modules%5Cexpo%5CAppEntry.bundle?platform=android&dev=true&hot=false"}, url="https://eth-goerli.alchemyapi.io/v2/API_KEY", code=SERVER_ERROR, version=web/5.6.1)]

The request shows up fine on my Alchemy dashboard and even gives me the output there, but I am unable to fetch any information from the request into my app and I have no idea why. For example, this is the response I am shown on my Alchemy dashboard:

{"jsonrpc":"2.0","id":47,"result":"0x71ade8"}

The response is totally fine but I am getting an error when using any functions that fetch the blockchain informattion

  1. Chosen as BEST ANSWER

    So, the API was returning the data correctly but my react native app wasn't recognizing it as a valid API call.

    In order to solve this problem, I simply downgraded the ethers library version to 4.0.49

    npm install [email protected]
    

    Now the API calls are working correctly and there is no error


  2. I think @ethersproject/shims fixes the issue as below;
