How to Disable generating sourcemap with expo build:web

I tried with putting

GENERATE_SOURCEMAP=false

in .env file, running command

set \"GENERATE_SOURCEMAP=false\" && expo build:web

and

"build": "GENERATE_SOURCEMAP=false expo build:web"

in scripts inside package.json nothing works. Devtools show my everything.

How can I protect my source from being exposed with expo:build?

I’m running into this problem as well - need to disable sourcemaps on production and the GENERATE_SOURCEMAP flag doesn’t seem to make a difference.

The way I solved the issue is, just deleting every .map files from the deployment folder. It works.
Thanks.
