Where's my error occur in my project? (How to find exact code line and its file name)

[topninja]

Hello team. I added logger in many places of my project And sometimes logger has error logs.

const pino = require('pino');
const path = require('path');
const logger = pino({
    prettyPrint: {
        messageFormat: '{filename}: {msg}',
        ignore: 'pid,hostname,filename',
    }
}).child({ filename: __dirname + '\\' + path.basename(__filename) });

I did like this so I can see which file, and its error message But I want to know which line produce this error so I can find issue easily. How to do this?

Thanks

p.s. logger.error(new Error('payload is not valid')) by this, I can get line but shows few more.. I want only 1 line

Remove messageFormat and you'll see a full stack trace.

I tried to do by removing messageFormat but shows only 1 line like above image.

Can you provide steps to reproduce? We often need a reproducible example, e.g. some code that allows someone else to recreate your problem by just copying and pasting it. If it involves more than a couple of different file, create a new repository on GitHub and add a link to that.

I added reproduction example already.

const pino = require('pino');
const path = require('path');
const logger = pino({
    prettyPrint: {
        messageFormat: '{filename}: {msg}',
        ignore: 'pid,hostname,filename',
    }
}).child({ filename: __dirname + '\\' + path.basename(__filename) });

logger.error("payload is not valid");

You are not creating an error, so there is no stacktrace. If you want to get a stacktrace, create an error.
