Error running nest generate locally

[crperezt]

Hi all -- I'm trying to run the app schematic locally, but running into this error:

An error occured:
Error: NOT SUPPORTED: keyword "id", use "$id" for schema ID

Failed to execute command: node ./src/my_schematics:app --no-dry-run --collection="./src/my_schematics" --no-skip-import --language="ts" --source-root="src" --spec --no-flat --spec-file-suffix="spec"

I just clone the repo to the ./src/my_schematics folder on a new nest project, and ran npm install then npm run build in that folder, then ran nest g -c ./src/my_schematics app from the root of my project, but I get the above error. Any clue what could be going on?
