Exercise tracker - learning resources

Hi everyone!

I’m buiding the exercise tacker for the APIs and microservices section. I am having a rather difficult time with it, so I’d like to know if you have further resouces to learn what’s necessary to solve it. I don’t think the lessons in freecodecamp were enough, at least for me. I keep getting weird errors all over the place :joy:

So would you please share your courses, readings, tutorials or anything that can help me build this?

Thanks so much!!

Ok :slight_smile:
I haven’t got really far:

Because I get this error:

Error: Can’t set headers after they are sent.

And I don’t know how to fix that.

But overall I have no idea what I’m doing tbh.
