NextJS - Sentry CLI Plugin: spawn ENOMEM

I have a working nextjs repo and I want to create an automated deployment. However, running yarn build:dev is sometimes failing and I don't have an idea of its cause. I'm thinking this is an issue with Sentry. Any ideas will help. Thanks.

usertest@user-test:~/user-app$ yarn build:dev
yarn run v1.22.17

$ SENTRY_ENV=testing next build

Failed to compile.
