Cannot build Shopware 6 admin with npm 8.11 - npm

Question

When running bin/build-administration.sh we get
npm ERR! code ERESOLVE
npm ERR! ERESOLVE could not resolve

We are using this versions:
$ npm -v
8.11.0
$ node -v
v16.15.1
and Shopware 6.4.11.1
With npm 8.5 it seemed to work.
I am wondering if this is a bug in Shopware or in npm?
I would guess something needs to be updated in Shopware?

run npm config set legacy-peer-deps=true in your project folder
