405 error encountered when using Fetch POST data to the server in Express and Node - looking for a solution

Question

I'm using Express and Node. Use Fetch to POST some data to the server. I'm getting a 405 error. I don't know how to solve this problem.

Answer 1

From what I can see in the screenshot, your node application is running on port 3000, but the error on the console indicates that you are getting a 405 error on localhost, but the port 5501.

Is it possible that you are trying to access the wrong URL?

Answer 2

Just get the node app from "app.listen" by editing:

fetch('api', options)

to

fetch('http://localhost:3000/api', options)
