Description

Our project is running on Angular 18 and we would like to migrate to 19. To do this, we tried to run the usual ng update but because of the usage of pnpm catalog protocol Angular CLI is unable to run the packages migration properly.

Minimal Reproduction

• Setup an angular 18 project inside a pnpm workspace
• Use pnpx codemod pnpm/catalog to move all dependencies in workspace catalog
• Try to run ng update @angular/core@19 @angular/cli@19
• See the actual error
