Error alpaca_trade_api.rest.APIError: insufficient non-marginable buying power

Hi @devs,
I am working on the alpaca crypto paper trading bot and it is showing me this error “alpaca_trade_api.rest.APIError: insufficient non-marginable buying power”
I have tried regenerating my API key but the error still prevails.
Appreciate your help.
