  1. Using "@json2csv/whatwg": "^6.1.3".
  2. node version 18.16.0 or running on chrome 113.0.5672.93
  3. Using json in angular application https://github.com/rianluoar/angular16-json2csv clone the angular application and run npm i. After installing node module run command "npm start". Open http://localhost:4200/ on chrome and click on download button.
  4. After clicking on download button getting below error in console json2-csv.service.ts:12 ERROR Error: Uncaught (in promise): TypeError: Failed to execute 'dispatchEvent' on 'EventTarget': parameter 1 is not of type 'Event'.

Just for testing purpose I removed (...args) from line 42 of TransformStream.js it started working as expected on my local system. @juanjoDiaz https://github.com/juanjoDiaz/json2csv/blob/main/packages/whatwg/src/TransformStream.js#L42

Hi @rianluoar ,

Yes. This is a known issue. Fixed in the upcoming typescript version that I've been trying to release since forever. I'll try to get it out asap.

I just released v7.0.0 which entirely rewrites @json2csv to typescript. This issue should be solved there.

Let me know if you find any other issues with it. This was a massive change.
