I've requested 20.15, but debug shows that 12.22.9 is actually used ### To Reproduce - rockcraft 1.5.2 stable or 1.5.2.post1+g983a391 edge - (not sure if important) an arm host or vm - try build (errors out), see the log or poke using `--debug` Observe that node version is v12.22.9 despite the requested latest or 20.15 or seemingly any. ### part yaml ```shell traefik-frontend: plugin: npm source-type: git source-depth: 1 source-tag: "v2.11.3" source: https://github.com/traefik/traefik npm-include-node: true npm-node-version: "node" build-packages: - nodejs - npm override-build: | npm install -g yarn && \ cd ./webui && \ # added --legacy-peer-deps to avoid dependency resolution errors with mocha (testing) npm install --legacy-peer-deps && \ # Build the bundle as per: # https://github.com/traefik/traefik/blob/84a081054688349fa4e2513599e3bf2395331492/Makefile#L66 npm run build:nc && \ # cleanup rm -rf node_modules ``` ### Relevant log output ```shell ... 2024-07-03 21:21:44.567 :: 2024-07-03 21:19:13.222 :: Get:15 http://ports.ubuntu.com/ubuntu-ports jammy-updates/universe arm64 libnode72 arm64 12.22.9~dfsg-1ubuntu3.6 [10.3 MB] 2024-07-03 21:21:44.567 :: 2024-07-03 21:19:14.202 :: Get:16 http://ports.ubuntu.com/ubuntu-ports jammy-updates/universe arm64 libnode-dev arm64 12.22.9~dfsg-1ubuntu3.6 [609 kB] 2024-07-03 21:21:44.567 :: 2024-07-03 21:19:14.245 :: Get:17 http://ports.ubuntu.com/ubuntu-ports jammy-updates/universe arm64 nodejs arm64 12.22.9~dfsg-1ubuntu3.6 [122 kB] ... 2024-07-03 21:21:44.574 :: 2024-07-03 21:21:37.268 :: npm WARN EBADENGINE Unsupported engine { 2024-07-03 21:21:44.574 :: 2024-07-03 21:21:37.268 :: npm WARN EBADENGINE package: 'traefik-ui@2.0.0', 2024-07-03 21:21:44.574 :: 2024-07-03 21:21:37.268 :: npm WARN EBADENGINE required: { node: '^20 || ^18 || ^16', npm: '>= 6.13.4', yarn: '>= 1.21.1' }, 2024-07-03 21:21:44.574 :: 2024-07-03 21:21:37.268 :: npm WARN EBADENGINE current: { node: 'v12.22.9', npm: '8.5.1' } 2024-07-03 21:21:44.574 :: 2024-07-03 21:21:37.268 :: npm WARN EBADENGINE } ... 2024-07-03 21:21:44.575 :: 2024-07-03 21:21:44.101 :: error traefik-ui@2.0.0: The engine "node" is incompatible with this module.
