23.7.13 -> 23.7.14 Regression with 'Type instantiation is excessively deep and possibly infinite'

[harry-gocity]

💥 Regression Report

I'm using next-i18next in a project with 7 namespaces. In upgrading that from 15.0.0 to 15.2.0 I started to see Type instantiation is excessively deep and possibly infinite with my useTranslation call.

I have narrowed this down to the underlying i18next dependency bumping from 23.7.13 -> 23.7.14. The issue persists with a bump to latest 23.10.0.

Last working version

Worked up to version: 23.7.13

Stopped working in version: 23.7.14

To Reproduce

I've tried to create a reproduction of this but have been unable to so far - but will keep trying to narrow down the issue. Sorry, I appreciate this isn't very helpful right now.

Expected behaviour

Type definitions to work as before.

Your Environment

• runtime version: Node 20 LTS
• i18next version: See above
• os: Mac
• any other relevant information

I saw from the release notes that the release was intended to fix types for array access. Are there any examples translation json structures that would be parsed differently before / after this release?

We really need a minimal reproducible example...
This was the change: #2101

Just as a heads-up: I'm currently sick and will likely not be able to look into this myself for at least a couple weeks; but as both of you correctly pointed out already anyway: without a minimal reproducible example, this is probably next to impossible to debug, anyway... :(

Yep, I completely agree, I'll get a reproduction sorted. I don't expect help from maintainers until then, fwiw
