I use Angular 8.2.3. I follow the example as described here: https://github.com/herodevs/herodevs-packages/tree/master/projects/lazy

When I hover the cursor to element, an error appears:

ERROR Error: Uncaught (in promise): Error created and attaching module async.

In the developer console, I see that the JS file is loaded successfully.

I tried turning on and off for Ivy, but without result.

Everything worked for me as well. However today I have the same error.

EDIT

I could somewhat reproduce this error. After installing:

npm install ngx-tree-data --save

I get warns.

and the module loader does not work anymore.
