unsatisfied authorization error while push transaction

Question

While using the push transaction I am getting the below error, Kindly help

{ "code": 500, "message": "Internal Service Error", "error": { "code": 3090003, "name": "unsatisfied_authorization", "what": "Provided keys, permissions, and delays do not satisfy declared authorizations", "details": [] } }

This is my smart contract code

#include <eosiolib/print.hpp> 

using namespace eosio; 

class hello : public contract { 

public: 
    using contract::contract; 
    [[eosio::action]] void hi( name user ) {
        print( "Hello, ", name{user});
    }
};

EOSIO_DISPATCH( hello, (hi))

Answer 1

Just import genesis account (eosio) keys in the wallet. - Make sure wallet is unlocked

cleos wallet unlock

Now import the keys which are fixed

eosio public key: EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
eosio private key: 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDe

So your command of importing key will be

cleos wallet import --private-key 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDe

All should be find after that.

Answer 2

Import eosio keys to wallet and then try to push transaction

Answer 3

Before doing push_transaction, there are few more steps to do

1. abi_json_to_bin- Convert the transaction into binary form(transaction packing)
2. get_info- To get the current block number
3. get_block- To get information about the latest block
4. unlock_wallet - Unlock your wallet(Make sure wallet is imported with required keys)
5. get_required_keys- Get the required keys from the wallet for signing the transaction
6. sign_transaction- Sign the transaction using data obtained from previous steps
7. push_transaction- Finally, push the signed transaction into blockchain

Make sure the wallet is imported with required keys. For detailed tutorial go to EOS-Tutorials
