Material UI

how are you serving your react app?

create react app?

Yes

do you have any build or start commands set in the service settings? if so, remove them

copy the nixpacks.toml and Caddyfile from this repo into your project

Just this one : CI=false npm run build. Ok did it

set a service variable CI=false instead

Error: reading input file: open Caddyfile: no such file or directory

RUN caddy fmt --overwrite Caddyfile

ERROR: failed to solve: process "/bin/bash -ol pipefail -c caddy fmt --overwrite Caddyfile" did not complete successfully: exit code: 1

did you copy both files, keeping the same filenames?

I thought so but it seems that my computer renamed CaddyFile to CaddyFile.txt that should solve the issue

It worked!
Can you tell me what the problems were?

you where trying to a development server

Alright, so don't use react script when deploying and you should be good

correct, react script has no way of running a production server
