Template Parse Erros Angular "<" (" with Django REST framework - django

Question

I've been trying to create a DRF API with an Angular front end for an existing project that I have. I've created a serializer for User and Device. I tried removing multiple pieces of the HTML component, managing to result in a different error, StaticInjectorError(AppModule -> DevicePostService).
I'm still pretty new to Angular so what it seems like the error is coming from is the fact that my devicepostservice is not getting served to the web page for some reason.
Console error:

Answer 1

Seems like you have a basic syntax error in your template
<button (click)="login()" class="btn btn-primary">Log In</button
should be
<button (click)="login()" class="btn btn-primary">Log In</button>
(note the final '>' character)
