Incompatible dependencies / not possible to use npc ci

[michi88]

I was using version 22 before and this fails now when installing because of updated dependencies. But even when installing the latest it does not work.

Box UI Elements requires immutable@^3.7.4
@box/box-ai-content-answers requires immutable@^4.0.0

We used to be able to override the incompatible versions in the past but it seems not to work anymore. Please fix this because we need to be able to do npm ci for consistent deployments. This can now only be installed with npm install --legacy-peer-deps which results in a lock file that npm ci does not accept. Or is there a way around this?

Steps to reproduce the problem:

$ npm --version
10.9.2

$ node --version
v22.13.0

The install works with legacy peer deps:

$ npm install box-ui-elements --save --legacy-peer-deps

But then nom ci still fails
