Please teach me about the IO function error reporting problem.

This is the first time that the company has been listed on the stock exchange.

This is the latest version of the.js test code: function main (() {exchange.IO("api",“GET”,"/api/futures/v3/instruments/BTC-USD-190927/book") }

function main(){ exchange.IO("api",“GET”,"/api/futures/v3/instruments/BTC-USD-190927/book",“size=50”) }

Both of the above test methods returned errors: main:3:15 - TypeError: Cannot convert GET to intWhat I don't understand is what the document says: Parameter values: httpMehod is a string type, request type "POST" or "GET", resource is a string type, path type, params is a string type, interaction parameter type.

I've been trying to get this to work for me.exchange.IO("api", “GET”, “/api/futures/v3/instruments/BTC-USD-190927/book”) Returns error:TypeError: IO() takes at most 3 arguments (4 given)So what's weird here is, given three parameters, the error is that I gave four parameters?

python test codeexchange.IO(’api’, ‘GET’, ‘/api/futures/v3/instruments/BTC-USD-190927/book’,‘size=5’) TypeError: IO (()) takes at most 3 arguments (5 given)So what's weird here is, given three parameters, you're saying I'm giving five parameters?
