uncaughtException: rollbar_1.default is not a constructor

[surisoko]

This error is thrown when I deploy my nodejs project

TypeError: rollbar_1.default is not a constructor
    at rollbarInit (/dist/rollbar.js:9:12)
    at Object.<anonymous> (/dist/app.js:28:39)

And my code:
rollbar.ts

const Rollbar = require('rollbar')

export const rollbar = new Rollbar({
  accessToken: MY_ROLLBAR_KEY,
  captureUncaught: true,
  captureUnhandledRejections: true,
})

app.ts

import { rollbar } from './rollbar'

app.use(rollbar.errorHandler())

nodejs: 16
express: 4.18.2
rollbar: 2.26.1

@surisoko Thank you for the report.

const Rollbar = require('rollbar')

should work when setting "module": "commonjs" in your tsconfig compilerOptions.

Node 16 supports ES modules, and allows setting "module": "ES2022" or other ES versions. In this case, the correct syntax is:

import Rollbar from 'rollbar';

In your tsconfig compilerOptions, you should also set "esModuleInterop": true.

This is covered in the doc here: https://docs.rollbar.com/docs/importing-or-requiring-rollbar

Hi @waltjones
I've tried import Rollbar from 'rollbar' with no luck, same error
My tsconfig.json:

"compilerOptions": {
    "module": "commonjs",
    "moduleResolution": "node",
    "esModuleInterop": true,
    "target": "ES2018",
    ...
}

@surisoko It looks like you might be setting "type": "module" in package.json?

[surisoko]

There is no such configuration in my package.json

The funny thing is that it doesn't work if I import rollbar from app.ts, but does work from other subfolders
