I have below configuration to take source as src, but it still takes app folder

{
"$schema": "https://json.schemastore.org/nest-cli",
"collection": "@nestjs/schematics",
"sourceRoot": "src",
"compilerOptions": {
"deleteOutDir": true
}
}

here is the build script:
"build": "NODE_ENV=production nest build src",

and I have pnpm-lock.yaml for sure in repo. but the error is:
0.923  WARN  Ignoring not compatible lockfile at /app/pnpm-lock.yaml

0.925  ERRPNPMNO_LOCKFILE  Cannot install with "frozen-lockfile" because pnpm-lock.yaml is absent
