enter image description here

If I specify only solana-client and solana-sdk, I get this error:

Please upgrade your solana cli to stable 1.13.4 And also in your smart contract (on chain) programs you are suppose to use solana-program library. solana-sdk and solana-client are for client side libraries

    The answer says to not use solana-client and solana-sdk in your on-chain program, and to use solana-program instead. You need to delete the other dependencies and use solana-program instead.
