I'm facing an issue with my dotnet core api with angular. I simply made a login form and a UserController to handle login requests with jwt but whenever i hit the "Login" button and call the UserController's Login method from my angular app with this:
this.http.post<any>(environment.baseUrl + `api/user/login`, user)
I always get the following message:
"The SPA default page middleware could not return the default page '/index.html' because it was not found, and no other middleware handled the request."
I'm looking for more than a solution on this one because i've been searching to fix it the whole day and i couldn't figure out how i could solve it. I looked at iis logs, eventviewer logs. I tried debugging and did a fair amount of internet research, but I can't find a proper way to actually handle this kind of error
Since the error is raised by the dotnet core framework, i don't really know how to determine if it's my controller that is broken or if i made a mistake while configuring services.
How do you usually figure this out? Thanks for your time and your help in advance ;)
