That's not a lot of detail to go on.

See also #8026.

Any chance you're not using the default index.html in which the required JavaScript bundles are inserted automatically, but instead are using some other means to insert the bundles?

(If yes, then see https://stackoverflow.com/a/41829100.)

@avbentem Yes, apologies for the lack of detail I was in a bit of a rush posting and was hoping it might be an obvious fix for someone! To elaborate a little it occurs in one of 2 almost identical components. It renders the page the first time around but if I hit refresh, it will give me those errors. If I go back a page and navigate to it again it will render properly again. The same error occurs if I make a change to a file and it reloads. Hopefully, that clarifies things a little? Oh and I'm using the default index.html. No customisations there...

I think this issue is a duplicate of #8026. Can you add a repro and details there please? With just the information here there isn't much we can do to address it.
