stylex.create Errors thrown when defining only null values in a declaration

[RimanDk]

The problem
Style objects that include only entries with null values result in stylex.create should never be called. It should be compiled away. exception.

How to reproduce
Steps to reproduce:

1. Create a React + TypeScript project with StyleX
2. Create a style block/declaration including only null values, f.ex:

const styles = stylex.create({
  test: {
    padding: null,
  }
});

3. Apply to any node in a given component

Code Sandbox example (expand console in the browser window - might need a reload to show up)

Expected behavior
Declared styles should be applied and no errors should be thrown

Environment (include versions). Did this work in previous versions?
Tested with 0.3.0 and 0.4.1 in a Vite project, using an unofficial StyleX Vite plugin didn't work with either version.

This seems like a bug with vite-plugin-stylex-dev, although I'm not sure what the issue might be since things do work when I add any other style.

To verify, I tried using vite-plugin-stylex which is another unofficial plugin. After manually forcing the plugin to use v0.4.1 of the stylex babel plugin, it seemed to work correctly even with just a single null style.

Here's a fork for your codesandbox example to see it working.

Thank you for the quick response! Sounds very reasonable - I will raise the issue with the plugin makers, then. Cheers.

I wrestled briefly with the other plugin you mentioned, but couldn't get it to work in my setup. Unfortunately, the fork you provided appears to be a 1:1 with my own example and is still using vite-plugin-stylex-dev.

@RimanDk Sorry about the link mixup. This should be the correct one.
