[Bug]: calling wallet_addEthereumChain throws error -32603

[doubleppereira]

Describe the bug

When trying to add a network from any dapp MM throws an unexpected error even though it added network.

Here is a codesandbox of the issue on add network: https://codesandbox.io/p/sandbox/connect-metamask-plkgo
this example adds gnosis network and MM throws an error -32603, message
:
"f is not a function"
stack
:
"TypeError: f is not a function\n at chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/background-0.js:1:105287\n "

Expected behavior

When adding a network from a dapp like:

 "method": "wallet_addEthereumChain",
 "params": [
  {
    chainId: "0x64",
    chainName: "Gnosis",
    rpcUrls: [
      "https://rpc.gnosischain.com"
    ],
    iconUrls: [
      "https://xdaichain.com/fake/example/url/xdai.svg",
      "https://xdaichain.com/fake/example/url/xdai.png"
    ],
    nativeCurrency: {
      name: "XDAI",
      symbol: "XDAI",
      decimals: 18
    },
    blockExplorerUrls: [
      "https://blockscout.com/poa/xdai/"
    ]
  }
],
});

like as provided by the documentation on https://docs.metamask.io/wallet/reference/json-rpc-methods/wallet_addethereumchain/ with valid configuration it shouldnt throw any error.

We require the handling of error in case the user rejects or we wrongly add a wrong configuration to add network
