Hmm. Are you using hotwire-livereload? I just updated that gem (1.1.0) and my sourcemap errors are gone.

I'm getting errors for sourcemaps on every request as well. I'm not sure why it's happening, but I assume it's because I'm using a non-stock configuration. i.e. I'm building two scripts - application.js and application-dev.js (only used in dev).

My scripts section for dev looks like:

"dev": "concurrently --kill-others yarn:dev:*",
"dev:css": "tailwindcss --watch -i ./app/assets/stylesheets/application.tailwind.css -o ./app/assets/builds/application.css",
"dev:js": "esbuild app/javascript/application.js --watch --bundle --sourcemap --outfile=app/assets/builds/application.js",
"dev:jsdev": "esbuild app/javascript/application-dev.js --watch --bundle --sourcemap --outfile=app/assets/builds/application-dev.js",

and in my Procfile.dev:
assets: yarn dev
