I have used angular-tree-component in my project.It does work in Chrome but not in IE11.
It gives following error.

package-lock.json

Hi ,
I am also facing same issue. Any workaround / solution for it ?
Hi, also have the same issue, any ideas?
mobx 5 doesn't support I.E. 11, it got updated here https://github.com/500tech/angular-tree-component/commit/0c336fdaf299ed9471d7cdd75ffbd1e2a86b5550
I forked to downgrade and we're using this version -> https://github.com/500tech/angular-tree-component/pull/776
maybe you can workaround with npm-shrinkwrap
Switched to version 8.0.0 and everything is fine
This is fixed in https://github.com/500tech/angular-tree-component/pull/776, but not yet released.
Downgrading to 8.4.1 worked for me.
thank you! that worked for me also 8.4.1
The MobX downgrade was merged and should fix this.
Please use angular-tree-component 8.5.4
