Making call to a contract fails

I have my contract deployed to basic-erc20.hash-rush.testnet account. It is just erc20 extended with minting and burnable extensions implementated on rust.

When I try to make a call, for example:

near call basic-erc20.hash-rush.testnet inc_allowance '{ "escrow_account_id": "facebook.testnet", "amount": "5" }' --accountId malkevych.testnet

I receive the message:

Scheduling a call: basic-erc20.hash-rush.testnet.inc_allowance({ "escrow_account_id": "facebook.testnet", "amount": "5" })
Receipt: baKLR7NHbUpSRgAr5GVdKXqkJs7PLKS6azHFz183wkN
        Failure [basic-erc20.hash-rush.testnet]: Error: Smart contract panicked: panicked at 'The required attached deposit is 33100000000000000000000, but the given attached deposit is is 0', src/lib.rs:462:13
Error:  GuestPanic [Error]: Smart contract panicked: panicked at 'The required attached deposit is 33100000000000000000000, but the given attached deposit is is 0', src/lib.rs:462:13

}

So then I found that I can attach gas using --gas param. So then I make another tx:

near call basic-erc20.hash-rush.testnet inc_allowance '{ "escrow_account_id": "facebook.testnet", "amount": "5" }' --accountId malkevych.testnet --gas 33100000000000000000000

So I tried to decrease the amount of gas:

near call basic-erc20.hash-rush.testnet inc_allowance '{ "escrow_account_id": "facebook.testnet", "amount": "5" }' --accountId malkevych.testnet --gas 33100000000000000      
Scheduling a call: basic-erc20.hash-rush.testnet.inc_allowance({ "escrow_account_id": "facebook.testnet", "amount": "5" })
Error:  InvalidTxError: {}

    at processTicksAndRejections (internal/process/task_queues.js:97:5)
    at async Account.signAndSendTransaction (/Users/bohdan_malkevych/.nvm/versions/node/v13.12.0/lib/node_modules/near-shell/node_modules/near-api-js/lib/account.js:115:22)

  type: 'InvalidTxError'
}

And again it is not successful.

All default tests are running ok, without any errors. Thanks in advance!

Using depositYocto worked for me.

You can retry the command like so:

near call basic-erc20.hash-rush.testnet inc_allowance '{ "escrow_account_id": "facebook.testnet", "amount": "5" }' --accountId malkevych.testnet --depositYocto "33100000000000000000000"

The original error message you got was:

The required attached deposit is 33100000000000000000000, but the given attached deposit is is 0

Note that this is coming from the contract itself. You can see the lines that throw this error:

assert!(
    required_deposit <= attached_deposit,
    "The required attached deposit is {}, but the given attached deposit is is {}",
    required_deposit,
    attached_deposit,
);

When using near-cli, you can add --help after a command to see what options you can pass. near call --help returns lots of info; the relevant bits here are:

near call <contractName> <methodName> [args]

Options:
    ...
    --gas                      Max amount of gas this call can use  [string] [default: "100000000000000"]
    --amount                   Number of tokens to attach  [string] [default: "0"]

Have you tried keeping gas at the default but setting --amount to 33100000000000000000000? The command would look like:

 near call basic-erc20.hash-rush.testnet inc_allowance '{ "escrow_account_id": "facebook.testnet", "amount": "5" }' --accountId malkevych.testnet --amount "33100000000000000000000"
