Windows here!

Funny, I tried first to reproduce on Powershell and there was no issue.

Then, I opened a regular Command Prompt and found that I could reproduce it.

The problem TypeError: Cannot use 'in' operator to search for 'lossless' in {quality:75}:

does not occur in powershell (weird!)
also occurs in node version 16.4.0
has the full stack trace:

TypeError: Cannot use 'in' operator to search for 'lossless' in {quality:75}
    at Object.toWireType (C:\Users\jcao2\dev\squoosh\libsquoosh\build\index.js:1:96950)
    at Object.encode (eval at new_ (C:\Users\jcao2\dev\squoosh\libsquoosh\build\index.js:1:104602), <anonymous>:10:26)

    at async MessagePort.<anonymous> (C:\Users\jcao2\dev\squoosh\libsquoosh\build\index.js:26:742)

Hmm, so further investigation showed me that using this command:

npx @squoosh/cli --webp "{\"quality\":75}" heaps.png (notice the double quotes and escaping)

makes it work on Windows Command Prompt. The root issue has something to do with CLI arg parsing?

Thanks, @PetrusVermaak.

I can’t reproduce this on MacOS or Linux. So I guess this is an issue with Windows. I don’t have a machine at hand, so if anyone wants to help here, that’d be awesome.
