Summary

I have an expo app in the subfolder of a mono repo setup (yarn workspaces). I haven't changed my deploy command or project structure which is the same as always and it's always worked fine. But today I tried to deploy and got some errors at the install stage, I clicked around and noticed that my entire repo had been uploaded to expo and not just the project subfolder like it usually is the case.

So I ran the eas inspect command to see what's actually being uploaded and sure enough the generated folder contained the whole repo.

Did anything change in a recent version that could have broken the use of this env var? I can confirm the other var I'm using EAS_NO_VCS is working because I see the yellow warning message like usual:

Using EAS CLI without version control system is not recommended, use this mode only if you know what you are doing.

My npm scripts:

"eas:inspect": "yarn pre-deploy && EAS_NO_VCS=1 EAS_PROJECT_ROOT=. eas build:inspect --platform ios --
"deploy:ios:dev": "yarn pre-deploy && EAS_NO_VCS=1 EAS_PROJECT_ROOT=. eas build --platform ios --clear-cache --profile development && yarn post-deploy"
profile production --stage archive --output ./eas.tmp --force && yarn post-deploy",
"pre-deploy": "tzx ../../scripts/tools/prepost-deploy.ts --predeploy",
"post-deploy": "tzx ../../scripts/tools/prepost-deploy.ts --postdeploy",

Managed or bare?

Update: I just found a workaround, if I use the absolute path of the project folder on my computer e.g. EAS_PROJECT_ROOT=/Users/foo/path/to/project/folder instead of the EAS_PROJECT_ROOT=. relative path, it works. I'll leave the issue open in case it helps tracking the regression but if you think it's not worth it feel free to close, the workaround is good enough solution for me.
