I am working on an EOS frontend Dapp with Scatter on local chain. I am getting a problem with transfer/deposit tokens from one account to another. After logging into scatter with "test1" and trying to transfer tokens from "test1" to "test2", I get the following error:

api error => undefined http://127.0.0.1:8888/v1/chain/push_transaction {"compression":"none","transaction":{"expiration":"2018-10-28T14:10:39","ref_block_num":22565,"ref_block_prefix":7727111,"net_usage_words":0,"max_cpu_usage_ms":0,"delay_sec":0,"context_free_actions":[],"actions":[{"account":"test2","name":"transfer","authorization":[{"actor":"test1","permission":"active"}],"data":"000000008090b1ca000000000091b1ca102700000000000004454f5300000000016d"}],"transaction_extensions":[]},"signatures":["SIG_K1_Kdrrfnn48GXVbBykes1WZGmwcb58Y4iLok3kAHbLANnjafJRqFCH5tpGy6Dt4SXwyWeFUaB8yaKa7Ud27v23nvaEJ3JxX9"]}

Error: {"code":500,"message":"Internal Service Error","error":{"code":3050003,"name":"eosio_assert_message_exception","what":"eosio_assert_message assertion failure"

Please help me to solve this. It would be great if anyone provided the code!

Your issue not come from setting scatter because it shows the error from smart contract that mean the action already executed. So it is either from your token's smart contract or your action. So please provide more detail your command action then i can help.

TO make sure, please check your command action with cleos

  • I am using the eosio.token contract's transfer function in my smart contract. I don't know this is the right way or not to write the transfer function. So if you have any other idea then please suggest. I think you are right, there is no issue from scatter because it's fetching the identity.

  • I need more information to help you. What data you put in your transaction? Which network you are using mainnet or testnet or localnet? Have you try with cleos, does it work?

  • I got reference from this link: eosio.stackexchange.com/questions/2277/… so that you will get an idea what i am trying to say. I am using localnet and just call the transfer function by the identity of scatter. I tried on terminal with command: cleos push action test2 transfer '[ "test1", "test2", "1.0000 EOS", "m" ]' -p test1@active , i get the following error : 982634ms thread-0 wasm_interface.cpp:929 eosio_assert ] message: unable to find key 982731ms thread-0 http_plugin.cpp:405 handle_exception ]

  • Have you create EOS token for your local network? If not please use following link developers.eos.io/eosio-cpp/docs/token-tutorial

You are pushing a transaction on the blockchain which is running on http://127.0.0.1:8888. Look at this API endpoint in your error, http://127.0.0.1:8888/v1/chain/push_transaction.

That means either you have to configure this network in scatter or you have to push the transaction on that blockchain server which is configured in Networks tab in Settings.

HTH.

  • I have already configured this network in scatter. The other functions in smart contracts are working fine but having problem with transfer function only. I don't know this is the right way but i am using the eosio.token contract's transfer function in my smart contract.

  • If you are using eosio.token to transfer via your contract, then you have to give correct permissions. follow this: eosio.stackexchange.com/questions/1774/…
