Data transforms error handling about json2csv HOT 3 OPEN

This does not happen in v6 which was just published as a separate package: https://www.npmjs.com/package/@json2csv/node

Although, the API has changed to make the async api more similar than the other.
Also, when piping to an output stream the promise method has been removed since it's trivial to wait for the end event and node nowadays even provides the pipeline method for that.
In v6 you can do:

const { pipeline } = require('node:stream/promises');

// ...

try {
  pipeline(asyncParser.parse(mockDataStream), process.stdout).catch(err => {
    console.log('Something happened');
  });
} catch (error) {
  console.log('Hello?');
}

or using the transform

const json2csvTransform = new Transform({ transforms: [dataTransform] }, { objectMode: true });

try {
  pipeline(mockDataStream, json2csvTransform, process.stdout).catch(err => {
    console.log('Something happened');
  });
} catch (error) {
  console.log('Hello?');
}

I haven't tested the code. It's just a quick guidelines.
If you have more issues with it I can look deeper into it.

Thank you @juanjoDiaz I didn't know that package existed, is this repo "deprecated" then?
I think I'll just migrate all the code from v5 to the new v6.

Yup. I'd consider it deprecated.
And I think that you'd do well moving to v6 🙂
