Why do I get an 'internal error' when using CCXT to create market orders in Coinbase API with Python?

Question

CCXT-coinbase create market order. I am trying to create market order on coinbase with CCXT.

coinbase {"error":"INTERNAL","error_details":"internal error","message":"internal error"}

It is resulting in this error

params1: {'side': 'BUY', 'params': {}, 'amount': '0.01','symbol':'BTC-USDT'}
params2: {'side': 'BUY', 'params': {}, 'amount': '0.01','symbol':'BTC/USDT'}

I tried both parameters, but it still returns an internal server error.

I need any help on passing proper params to create market orders.
