🐛 Bug: Jstz server cannot process POST requests with body. erro of json deserialization

[zamrokk]

Is there an issue with body: Uint8Array on the POST command ?

If I get a body from a response on the jstz node, I can extract it this way on my webapp and it works
Buffer.from(result.body).toString()

But if I pass the body on a POST call like this one, then I have an error

const result = await new Jstz(endpoint).run(user, {
        uri: uri,
        method: "POST",
        body: Buffer.from(JSON.stringify({
          option,
          amount
        }))

=>

[HTTP/1.1 400 Bad Request 3ms]
Json deserialize error: invalid type: map, expected a sequence at line 1 column 404

I don't even hit the smart function otherwise, I should see a log on it, I suppose that it is the Jstz node that is not able to process the POST request

I added more logs and it seems that the problem is on the Jstz Rust code (I cannot debug).
You can reproduce it : https://github.com/zamrokk/polymarktez
Redeploy the index.ts contract from the root directory to Jstz node
2. then point to your new contract address on the ./polymarktez/src/App.tsx l10 const DEFAULT_URI = "tezos://tz1iLrb3CbYjuBQBvhKGj5SpuyXAjzK63Jps";
3. send money to tz1eVqP1XNL9SCrrgkXgV5ZcteSULwiykDZ8 (the default user)
On the bottom button of the page, you have a simple PING call, just to check that all is fine and :large_green_circle:
If :large_green_circle:, then select an amount and click on button BET
you should receive this on the browser console and no logs on the smart function traces
