How do I catch a specific async/await error from package?-CodePudding

I have tried many ways to try and catch this specific async/await error from a package. I can't seem to catch a specific error. For other errors, it catches it but from this package, node.js does not catch it for some reason. (Sorry if the code is not formatted correctly or has silly mistakes I'm just typing it here.)

I have tried error , error.message, error.code, error.stack, error.toString(), and error.message.toString().

All of the above do not work to catch my error.

Using Try Catch

async function main(){
try {
await testExample();
 console.log('Finished!');
} catch (error){
if(error == 'specific error) {
throw new Error('an error has occured');
} else {
console.error(error);
}}}
main();

Using Try Catch Along with .catch attached to function

async function main(){
try {
await testExample().catch(function (error) {
if(error == 'specific error) {
throw new Error('an error has occured');
}
});
 console.log('Finished!');
} catch (error){
if(error == 'specific error) {
throw new Error('an error has occured');
} else {
console.error(error);
}
}}
main();

Using Try Catch Along with .catch, attached to main

async function main(){
try {
await testExample();
 console.log('Finished!');
} catch (error){
if(error == 'specific error) {
throw new Error('an error has occured');
} else {
console.error(error);
}
}}
main().catch(function (error) {
if(error == 'specific error) {
throw new Error('an error has occured');
}
});;

Using await-to-js

const to = promise => promise.then(res => [null, res]).catch(error=> [error|| true, null]);
async function main()
{
    var [error, success] = await to(testExample());
    if(error){
        if(error == 'specific error) {
throw new Error('an error has occured');
} else {
console.error(error);
}
    }
        if(success){
     console.log('Finished!');
main();   
});

Making a promise

async function main(){
await new Promise((resolve, reject => {
   testExample();
}).catch(function (error) {
 if(error == 'specific error) {
throw new Error('an error has occured');
} else {
console.error(error);
}
});

console.log('Finished!');
}
main();

Uncaught Exception

process.on('uncaughtException', function(error) {
   if(error == 'specific error) {
throw new Error('an error has occured');
} else {
console.error(error);
}
});

The source of your problem can be found here: https://github.com/fawazahmed0/youtube-uploader/blob/c2a33b0b680db2086be6d4b90a91b0157dca70eb/src/upload.ts#L658-L663

The error you want to catch is thrown in changeHomePageLangIfNeeded, but the linked code shows the error is caught and logged, but it isn't passed upstream to your code.
