This reproduction repository demonstrates a warning happening when using the Zimic CLI in Node.js 22.
-
Install the dependencies:
pnpm install
-
Run the typegen CLI:
pnpm typegen:github
Even though the command executes successfully, a warning about punycode being deprecated is shown:
$ NODE_OPTIONS=--trace-deprecation pnpm typegen:github
(node:23082) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.
