Error: no matching package named 'pallet-contracts-rpc' found

Question

I am trying to add the pallet-contracts-rpc dependency but keep getting this error.

''' error: no matching package named pallet-contracts-rpc found location searched: https://github.com/paritytech/substrate.git?branch=polkadot-v0.9.32 required by package node-template v4.0.0-dev (/home/kaioh/DeSign-/node) '''

I have also tried comparing with substrate contracts node template https://github.com/paritytech/substrate-contracts-node/tree/v0.23.0 and I see its not implemented in their node/cargo.toml file. I am using polkadot version 0.9.32.

This was removed in #12358, You no longer need to add the RPCs. Have a look at this as an example.

Porting Guide

The high level contracts API in polkadot.js already uses state_call so upgrading to the latest version here is enough. If you are using api.rpc.contracts directly you need to switch to api.call.contractsApi.
