I wrote a script that will invoke a function on a blockchain that returns a value. I have to collect these values from 0 to 5999. Unfortunately, several dozen values do not exist, and the loop encountering them stops the operation. How to prevent it?
let uriArray = [];
for (let tokenId = 0; tokenId < 5999; tokenId++) {
let result = await Gateway.tokenURI(tokenId);
console.log(result);
uriArray.push(result);
if (result = '') {
continue;
}
}
Use a try-catch, it is stopping I think every time there is a request error.
let uriArray = [];
for (let tokenId = 0; tokenId < 5999; tokenId++) {
try{
let result = await Gateway.tokenURI(tokenId);
console.log(result);
uriArray.push(result);
}catch(e){
console.log(e)
}
}
