Topic: Chart.js: Uncaught TypeError: Cannot read property 'moment' of undefined
ak.leimrey pro asked 6 years ago
Expected behavior: I created an entirely new project from scratch and added all the assets and styles and toyed around a little. Then I noticed in the console, that there was an error. I'm using Angular 8 and the most recent version of MDB and Chart.js 2.8.0
*Actual behavior*The application should start without throwing a type error

I got the same error after I updated my existing project to Angular 8, I'm also using Chart.js 2.8.0.

The worst part is, if you downgrade the Chart back to 2.7.4 you get a different error, now citing the easy-pie-chart as an error. That's what basically ruins Front-End development for me.

Guys,
This problem is not caused by our product. There's something wrong with Charts or Moment libraries, that the moment is undefined error is on.
Could you please provide me with steps, how can I reproduce this case? I have tried to reproduce it using blank Angular 8 app with MDB Angular 8 and Charts.js 2.8.0.
I have copied the basic line chart example from our docs, and my browser console is clear - there's no such problem.
Best Regards,
Damian

I started a new project again...
Currently it's Angular 8.1.0
After that I ran an installation of mdb and chart.js and kept the configuration and installations as minimal as possible
I can use the Chart.js without including it in my scripts in the angular.json
, so I can only assume that there is an issue with either Chart.js in conjunction with the mdb chart module. To avoid any issues with the imports, I only included the import { MDBBootstrapModulesPro } from 'ng-uikit-pro-standard'
. Deleting and re-installing the node packages hasn't done anything to help.

Guys,
There's some strange problem with Chart.js@2.8.0
. You have to use some older version: 2.5.0 - 2.7.3 are working fine.
