[SOLVED] 1Inch plugin, errors when using bsc network

Moralis General
#1

Hi everyone,

i use
const serverUrl = “https://uqppy6hj42wj.usemoralis.com:2053/server”;
const appId = “Vekfg0LulQYGrKA1CvfgRjhktqCQD7wMXNIHmoqv”;

I downloaded the code from https://moralis.io/how-to-create-a-dex-in-5-steps/, I created a bsc minnet server, while with chian eth it works, changing to bsc gives me the error

error = new _ParseError.default(errorJSON.code, errorJSON.error);

Uncaught (in promise) Error: [object Object]
at handleError (moralis.js:26415:17)

can you share the parameters that you used for hasAllowance function?

#11

solved by putting fixed tokens, but am I wrong something that gets me wrong in the function?

#12

the problem is BNB token

#13

what is the problem with BNB token?

#14

gives me this address to swap 0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

#15

this is list token function

async function listAvailableTokens() {
const result = await Moralis.Plugins.oneInch.getSupportedTokens({
chain: “bsc”, // The blockchain you want to use (eth/bsc/polygon)
});
tokens = result.tokens;
let parent = document.getElementById(“token_list”);
for (const address in tokens) {
let token = tokens[address];
let div = document.createElement(“div”);
div.setAttribute(“data-address”, address);
div.className = “token_row”;
let html = <img class="token_list_img" src="${token.logoURI}"> <span class="token_list_text">${token.symbol}</span> ;
div.innerHTML = html;
div.onclick = () => {
selectToken(address);
};
parent.appendChild(div);
}
}

#16

this could be the address used for 1Inch as a way to represent BNB that is a native currency

#17

ok thanks, is there a function to convert it?

#18

You need to fix this by replacing it with this

if (currentTrade.from.symbol !== "BNB") {
#19

I tried, it goes wrong

#20

Which token are you swapping from and which token are you swapping to ?

#21

For example if I use cake and usdt, everything is ok, if I use bnb from what I understand it gives me the native address and goes into error

#22

1Inch plugin works fine with BSC. You can try check This code and compare with yours.
