Hi @jlarmstrongiv, is this about the dev branch or the currently released v0.5.0?

[jlarmstrongiv]

Hi @LeaVerou this issue is about colorjs.io@0.5.0 with typescript@5.5.2

[LeaVerou]

Ah okay. We've made some major changes wrt typing in v0.6.0 and we’re still not done. We’ll do an alpha soon, please check it out to see if you still have this issue?

I was able to patch colorjs.io@0.5.0 like this:

This seems to unblock typescript 5.4 → 5.5 migration. @LeaVerou WDYT of releasing 0.5.1 with this patch?

[jlarmstrongiv]

Sure 👍 Let me know when you make an alpha release of v0.6.0 or a patch release of 0.5.1 and I’ll give it a go

@jlarmstrongiv Could you check whether this error still happens on v0.5.2?

[jlarmstrongiv]

@MysteryBlokHed thank you! I can confirm the error is resolved on v0.5.2 👍
