Not found error with Express route but it works!

[frederikhors]

I have a problem with my express app:

https://glitch.com/edit/#!/enthusiastic-velociraptor

When I navigate to GET /graphql it gives me Playground but in console I have a Not found

Why?

Reproducible with these steps:

• go to: https://glitch.com/edit/#!/enthusiastic-velociraptor
• see the code and open console
• go to: https://enthusiastic-velociraptor.glitch.me/graphql
• Graphql Playground works but in console you have "Not found" error!

I don't get it, I would check the network tab. Not Found on the base route shows up because there isn't a favicon, but that's typical if you don't handle that case. No issue other than the favicon on the base route for me.

[frederikhors]

Not. It's not the favicon the problem. Try to go back and forward in the browser!

It looks like you are adding a middleware on all routes, to call 404?

The error handler in Express is only invoked when it has 4 arguments (err, req, res, next).

Or you can add a catchall to the app stack, like link mentioned below. Quick glance, may not be correct.

I think I'm good as it is. Because I started a new express-generator app with:

express --view=pug myapp

and it wrote these files:

./app.js:

and routes/index.js:

You can try it with:

• npm install express-generator -g
• express --view=pug myapp

I have and I think the problem is just with apollo-server.

I found this problem: https://stackoverflow.com/questions/51826711/express-js-error-handler-doesnt-work-if-i-remove-next-parameter

But now the error handler with next works, and I have the same problem with different error:

Error: /app/views/error.hbs: Can't set headers after they are sent.

Reproducible with these steps:

• go to: https://glitch.com/edit/#!/enthusiastic-velociraptor
• see the code and open console
• go to: https://enthusiastic-velociraptor.glitch.me/graphql
• Graphql Playground works but in console you have the error!

Closing this for now as it's quite old and it seems to be an error in how you're using express. If you still need help feel free to reopen and let us know updated steps on how to reproduce it!
