User resolves production error with sanity-plugin-page-tree integration

Hello, I am trying to intergrate @q42/sanity-plugin-page-tree, it is working in development, but I am getting this error in production. Can you anyone help me

This may be related to a bug in

v2.9.0

of

@sanity/ui

. Can you please run

npm ls @sanity/ui

to confirm, and if you are, run

npm upgrade @sanity/ui

to get to

v2.9.1

(which fixed the issue).

thank you so much, it worked
