Nest CLI fails to generate a service | NestJS | Page 1

Hi everyone! I'm having trouble generating a new service in my NestJS project. When I run nest g service <service-name>, I get this error:
.

Error: (0, util_1.isNullOrUndefined) is not a function

Failed to execute command: node @nestjs/schematics:service --name=<service-name> --no-dry-run --no-skip-import --language="ts" --sourceRoot="src" --spec --no-flat --spec-file-suffix="spec"

I've tried reinstalling @nestjs/schematics, clearing the node_modules folder, and checking my tsconfig.json file, but nothing seems to work. Any help would be greatly appreciated!

Here are some details that might be helpful:

My NestJS version: 10.4.5

My Node.js version: 23.1.0

Thanks in advance!

Probably not the reason, but unless you are testing Node itself or some new feature in Node, you should stick to even numbered Node versions, even for development. 🙂

#

isNullOrUndefined from node:util doens't exists in node v23 anymore
that's why

#

so you can use nodejs v22 or wait for this PR to get merged: https://github.com/nestjs/schematics/pull/1918
