Cannot pass MichelsonMap as smart contract method parameter

Question

I have the following smartPy code deployed to a contract:

@sp.entry_point
def add(self, id, data_raw):
    sp.set_type(id, sp.TString)
    sp.set_type(data_raw, sp.TMap(sp.TString, sp.TString))
    
    self.data.mapping[id] = sp.record(
        data = data_raw,
    )

Now I want to call this contract with Taquito like this:

const id = "test_id"
const storageMap = MichelsonMap.fromLiteral({
    "1": "Test",
    "2": "Test2"
})

return tezos.wallet.at(accountSettings.contractAddress)
    .then((contract) => {
        reportResult("Sending...", "info", "#result-bar");
        return contract.methods.add(id, storageMap).send();
    })
    .then((op) => {
        reportResult("Waiting for confirmation...", "info", "#result-bar");
        return op.confirmation(1).then(() => op.hash);
    })
    .catch((error) => {
        reportResult(error.message, "error", "#result-bar");
    });

But I get the error [data_raw] Value must be a MichelsonMap. Is there an issue with me passing the MichelsonMap to a contract entry point? I see this is viable here, but I cannot see the contract example.

Edit 1: This is what I get when console.log(storageMap)

You can use michelson-sdk (Taquito example) to generate the Michelson values (Micheline or Michelson JSON).

You want something like this:

import { Record, String, Map } from "@tezwell/michelson-sdk/literal";

const storage = Record({
  id: String("test_id"),
  data_raw: Map([
    [String("1"), String("Test")],
    [String("2"), String("Test2")]
  ])
});

console.log("Michelson JSON: ", storage.toJSON());

In my case, the main problem was in SmartPy inverting the parameters of my generated method. So while I defined the following method:

add(id, storageMap)

On chain it was generated as

add(storageMap, id)

I'm not sure if that's a SmartPy bug or is by design, but what I called in Taquito and worked is this:

return contract.methods.add(storageMap, id).send();
