The following appears periodically (every few seconds) in the JavaScript console.
```plaintext
Failed to register/update a ServiceWorker for scope ‘http://localhost:3000/’: Load failed with status 500 for script ‘http://localhost:3000/service-worker.js’.
```
The terminal output looks like this:

This makes it quite annoying finding the correct logger statements. How do I get rid of it?

Looks like you have force\_https enabled. Try running `bin/rails c` it will give you a hint at what to do to fix it 😇

Going to the settings shows “force https” as being disabled. I haven’t changed any discourse setting or configuration after cloning the repository and running it. I’ve just worked on a plugin. No other files were changed.
Running the command `bin/rails c` doesn’t provide any hint that seems to be relevant, either. Maybe it’s something else?

Did you compile assets in your dev environment at some point? You may still have an assets manifest file that can cause this. Try clearing your `public/assets` folder.

No such directory exists. Investigating this more closely, it turns out that this is precisely the problem.
```bash
mkdir public/assets
```
Creating the directory solves the issue. There probably should be a check against this somewhere, right?

Oh weird. Looks pretty minor since it’s only affecting dev envs, but we’ll get this fixed.

Fixed, development service workers should act better without that directory - thanks for reporting this! 🍍
