Great post, congratulations! I'm stuck on error 400 in the last step: node server.js ("'input' is a required property", 'invalid\_request\_error'). Any support?

[Fandy Aditya Wirana](https://hashnode.com/@fandyadityaw) Hi, you are right, I just needed the input (i.e. the q param), but did not expect to break the code trying to access localhost:9000. Thanks for your reply.
