A mandatory parameter was not sent, was empty/null, or malformed.

always getting this error:
{
“status”: “error”,
“message”: {
“code”: -1102,
“msg”: “A mandatory parameter was not sent, was empty/null, or malformed.”
}
}

Was someone got into it? what am I doing wrong?

Debug and make sure that the sent request has all the mandatory parameters and with the expected type format, you can use https://github.com/binance-exchange/binance-signature-examples if you need examples.

never mind
I wrote timeStamp instead of timestamp
