I would like to use the angular bootstrap typeahead linkToTypeahead in an angular5 app. But I keep getting the following error(s):
ERROR TypeError: Object(...) is not a function

I copied the Simple Typeahead code from the website link.

What I have tried so far:
- reinstalled node_modules with npm -- does not help
- Started a brand new project with the angular CLI and tried out the code there -- does not help.
Any help is greatly appreciated!
