Web3js Javascript Returned error: execution reverted

I have my own BSC node running for scraping data, sometimes there is a token that does not have the standard token info functions like name, symbol, totalSupply and decimals and my scraper will throw a error "Returned error: execution reverted". now I can't find a way to prevent from stopping the scraper if I get this error. I just want the scraper to ignore that token if it gets the error.

Solution

  • For anyone who is interested. basically this is a double but I can not delete my question.

    What I did to solve my problem is

    await contract.methods.totalSupply().call().catch((err) => {
 return;
});

    web3js can have a catch() to catch the errors.
