  ]
}
Solution

  • This error indicates that nest cli command is not found in the firebase functions environment.

    This can be due to npm install ignoring devDependencies.

    Install @nestjs/cli with npm i --save @nestjs/cli to move this line

    "@nestjs/cli": "^10.3.0"

    from devDependencies to dependencies.

    Then attempt to deploy again.
