this resolved my issue :
create this json file : .env-cmdrc.json
{
  "development": {
    "NEXT_PUBLIC_TOKEN_TEST_1": "$2a$12$Deoyoudsgsdgsdgdsgdsgsdg546895363068"
  },
  "production": {
    "NEXT_PUBLIC_TOKEN_TEST_1": "$2a$12$Deoyoudsgsdgsdgdsgdsgsdg546895363068"
  }
}



script command :
 "scripts": {
    "dev": "env-cmd -e development next dev",
    "build": "env-cmd -e production next build",
    "start": "env-cmd -e production next start"
  }
