I'm not sure if this is a Node question or an Azure App Service question, but here goes:

I have a Node/Express app with two routes:

router.get("/users", checkAuthHeader, userController.getUsers);
router.post("/users", checkAuthHeader, userController.createUser);

On my local, this runs exactly as expected. GET /users returns a list of users, while POST /users creates a new user from the request body.

However, when I deploy this to Azure (vanilla setup of Azure App Service), any request to /users hits the request handler for GET /users, regardless of request method.

I have no idea why this is happening.
