wallet_invokeSnap - adding an extra attribute to request fails

[javaspeak]

Code like this works:

await window.ethereum.request({
    method: 'wallet_invokeSnap',
    params: { snapId: defaultSnapOrigin, request: { method: 'authorizeUTUSnap' } },
  });

However if I add an extra request attribute it does not:

await window.ethereum.request({
    method: 'wallet_invokeSnap',
    params: { snapId: defaultSnapOrigin, request: { method: 'authorizeUTUSnap', token: '1234' } },
  });

It complains that it does not like token:

An error happened: Invalid JSON-RPC request: At path: token -- Expected a value of type never, but received: "1234".

How do we pass additional request properties from site to the snap?

I think am missing something very basic here.

Thank you

You are passing the params incorrectly, it should be a nested object with key "params". It should look like:

await window.ethereum.request({
  method: 'wallet_invokeSnap',
  params: {
      snapId: defaultSnapOrigin,
      request: {
        method: 'authorizeUTUSnap',
        params: {
          token: '1234'
        }
      }
  },
});
