Verifying source maps locally is not possible

[vladinko0]

I wanted to verify my source maps locally and went through this guide.

I installed source-map globally with npm install -g source-map
Then I lunched:

const fs = require('fs');
const path = require('path');
const sourceMap = require('source-map');

// Path to file that is generated by your build tool (webpack, tsc, ...)
const GENERATED_FILE = path.join(
    '.',
    '/platformBuilds/dai_web/.next/static/chunks/pages/_app-9c6cc7df74562253.js.map'
);

// Line and column located in your generated file (for example, the source
// of the error from your minified file)
const GENERATED_LINE_AND_COLUMN = { line: 1, column: 10 };

const rawSourceMap = fs.readFileSync(GENERATED_FILE).toString();
// console.log('+++ rawSourceMap', rawSourceMap);
new sourceMap.SourceMapConsumer(rawSourceMap).then((smc) => {
    const pos = smc.originalPositionFor(GENERATED_LINE_AND_COLUMN);

    // You should see something like:
    // { source: 'original.js', line: 57, column: 9, name: 'myfunc' }
    console.log(pos);
});

But I get Error:

new sourceMap.SourceMapConsumer(rawSourceMap).then((smc) => {
                                              ^

TypeError: (intermediate value).then is not a function

How can I solve it?
