React App Build error in peer depency

As I am trying to set up a react app thought the apps manager, the build logs inform me about a peer dependency from some of the libraries.

I solve this problem locally by using npm i -f, but trying to deploy the app, the systems uses npm ci and I have zero knowledge on how to change that.

Any way to tell the system which command to run when booting the app?
