Error 500 on /studio/add-link

[Ti-Tom]

When adding a link (url = /studio/add-link), the Yaml lib seems to be missing when doing a composer install --no-dev.
The error appeared on the latest version of the docker image.

A composer install solves the problem but install unnecessary libs.

Same issue. After trying the "compose install" the page started working, sort of, but not properly. I have a spinny thing on the page that doesn't finish. As the last changelog references removing a discontinued dependency, it's likely that doing so broke something.
