ionic resources service was shut down long ago, now the CLI uses local generation, but you have to update ionic CLI

npm uninstall -g ionic
npm install -g @ionic/cli

I don’t want to update my cli. Any other way?

no, there is no other way

the new CLI is still compatible with old projects, there is no reason to not update
