Why near-cli can't find my contract method?

So I have this function implemented for my Contract

#[payable]
fn send_message(mut self, message: &str, receiver: &str) {

When I try to call it using near-cli

near call v1.messenger.ijelis.testnet send_message '{"message": "test","sender": "iejlis.near"}' --account-id ijelis.testnet

It gives me out this

Scheduling a call: v1.messenger.ijelis.testnet.send_message({"message": "test","sender": "iejlis.near"})
Doing account.functionCall()
Receipt: DDXubobUugwsGnr9GqXxMv7PJqT3YsLjTn14xWML4vx

      executor_id: 'ijelis.testnet',
      status: [Object],
      metadata: [Object]
    }
  }
}

What Am I doing wrong?

EDIT: I tried to deploy it using near-create-app interface, and everything worked fine.

Ensure you use #[near_bindgen] derive macro on your contract impl block to make pub contract methods visible.

seems you did not deploy the contract to this account.

check like this:

1. is there anything deployed to the account?

Use NEAR CLI to quickly view account state (https://docs.near.org/docs/tools/near-cli#near-state)

near state v1.messenger.ijelis.testnet send_message

Result

{
  amount: '2099882635532834400000000',
  locked: '0',
  code_hash: 'E8jZ1giWcVrps8PcV75ATauu6gFRkcwjNtKp7NKmipZG',
  storage_usage: 268,
  storage_paid_at: 0,
  block_height: 74201501,
  block_hash: '46fdR4oFfEDDuNmLMM8Le6FbKPR3VG5zzNni7u9uE3XQ',
  formattedAmount: '2.0998826355328344'
}

Conclusion

Yes, the account has something deployed to it because the value of code_hash is not the default 11111111111111111111111111111111 but E8jZ1giWcVrps8PcV75ATauu6gFRkcwjNtKp7NKmipZG which is a base58 encoded sha256 digest of the contract byte code, a fingerprint of the data deployed to the available "contract slot" on the account

2. so what is deployed to the account exactly?

Use the API to view contract code: https://docs.near.org/docs/api/rpc/contracts#view-contract-code

http post https://rpc.testnet.near.org jsonrpc=2.0 id=dontcare method=query \
  params:='{
    "request_type": "view_code",
    "finality": "final",
    "account_id": "v1.messenger.ijelis.testnet"
  }'

Result

{
    "id": "dontcare",
    "jsonrpc": "2.0",
    "result": {
        "block_hash": "48uCNbhhB9FSg35bJgMDvTpjS5f9n4jrnU4MmMmbHsqj",
        "block_height": 74201992,
        "code_base64": "AGFzbQEAAAAEBQFwAQEBBQMBABAGGQN/AUGAgMAAC38AQYCAwAALfwBBgIDAAAsHJQMGbWVtb3J5AgAKX19kYXRhX2VuZAMBC19faGVhcF9iYXNlAwI=",
        "hash": "E8jZ1giWcVrps8PcV75ATauu6gFRkcwjNtKp7NKmipZG"
    }
}

Conclusion

AGFzbQEAAAAEBQFwAQEBBQMBABAGGQN/AUGAgMAAC38AQYCAwAALfwBBgIDAAAsHJQMGbWVtb3J5AgAKX19kYXRhX2VuZAMBC19faGVhcF9iYXNlAwI= looks way too small to be a contract, especially one written in Rust (they're usually a little bigger than AssemblyScript contracts)

This base64 encoded string decodes to the following WAT

(module
  (table $T0 1 1 funcref)
  (memory $memory (export "memory") 16)
  (global $g0 (mut i32) (i32.const 1048576))
  (global $__data_end (export "__data_end") i32 (i32.const 1048576))
  (global $__heap_base (export "__heap_base") i32 (i32.const 1048576)))

So the contract you think is there is not actually there.

Solution

Deploy the contract to the account v1.messenger.ijelis.testnet

Note: the WAT above was generated in two steps:

(1). echo "AGFzbQEAAAAEBQFwAQEBBQMBABAGGQN/AUGAgMAAC38AQYCAwAALfwBBgIDAAAsHJQMGbWVtb3J5AgAKX19kYXRhX2VuZAMBC19faGVhcF9iYXNlAwI=" | base64 -d > contract.wasm

(2). upload Wasm file to https://webassembly.github.io/wabt/demo/wasm2wat/
