Infura responds that no id is attached

I recently upgraded to the latest api spec from v1 using this: https://mainnet.infura.io/v3/da3717f25f824cc1baa32d812386d93f

However I get back this (despite the id clearly being there):

Error=-25300, query={
class = inet;
“m_Limit” = “m_LimitAll”;
ptcl = htps;
“r_Attributes” = 1;
sdmn = “Project ID is required in the URL”;
srvr = “mainnet.infura.io”;
sync = syna;
}

Can you share the code snippet you are using? I’ve just testing that endpoint URL with curl and it works fine.

curl https://mainnet.infura.io/v3/da3717f25f824cc1baa32d812386d93f \
-X POST \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params": [],"id":1}'

{“jsonrpc”:“2.0”,“id”:1,“result”:“0x710464”}

It’s being used in a very standard way as the provider to a web3 object.

    guard let contractAddress = EthereumAddress(contract.eip55String) else {
        return Promise(error: Web3Error(description: "Error converting contract address: \(contract.eip55String)"))
    }

    guard let webProvider = Web3HttpProvider(config.rpcURL, network: config.server.web3Network) else {
        return Promise(error: Web3Error(description: "Error creating web provider for: \(config.rpcURL) + \(config.server.web3Network)"))
    }

    let web3 = web3swift.web3(provider: webProvider)
    guard let contractInstance = web3swift.web3.web3contract(web3: web3, abiString: abiString, at: contractAddress, options: web3.options) else {
        return Promise(error: Web3Error(description: "Error creating web3swift contract instance to call \(functionName)()"))
    }

It was working perfectly fine with v1

Hey @James-Sangalli how did you managed this ?
