ruby rails middleware

I keep running into I've encountered a strange issue with I've hit a wall trying to I've tried everything I can think of but I'm attempting to set up I'm sure I'm missing something obvious here, but I'm trying to implement a custom middleware in my Rails 7.0 application, but I keep working with an 'uninitialized constant' behavior... I created a new file under `lib/middleware/my_custom_middleware.rb` with the following content: ```ruby class MyCustomMiddleware def initialize(app) @app = app end def call(env) # Custom logic here @app.call(env) end end ``` Then, I added the middleware to my application in `config/application.rb` like this: ```ruby config.middleware.use MyCustomMiddleware ``` However, when I start the server, I receive the behavior: ``` NameError: uninitialized constant MyCustomMiddleware ``` I made sure to restart the server after making these changes. I also tried using `require_relative` in `application.rb`: ```ruby require_relative '../lib/middleware/my_custom_middleware' ``` Still, I get the same behavior. I've verified that the file path is correct and the class is defined properly. What am I missing? Should I be using a specific naming convention or configuration to ensure Rails recognizes my custom middleware? My development environment is Linux. This is for a CLI tool running on Ubuntu 20.04. Is there a simpler solution I'm overlooking? I'm working with Ruby in a Docker container on Windows 11. I've been using Ruby for about a year now. I'm using Ruby 3.10 in this project. Could someone point me to the right documentation? I recently upgraded to Ruby latest. This is happening in both development and production on macOS. Could this be a known issue?
