'Wrong number of arguments' when deploying ERC20_c on test network

[trictrac 0]

Hello,

I'm new to this network and I'm trying to find out whether it's worth the trouble developing contracts on the Elrond network and I must say that I'm impressed about/by the tooling offered by Elrond. But right now, I'm stuck in something: I was  trying to deploy the example ERC20_c on the test network, but the procedure fails with the message 'wrong number of arguments' as displayed in transaction hash 970fbb8cd5e6567c245d468663deed87119c51f8d7923d5d2cd1199eb8b6d70c on the test network. Does anyone know what that message signifies. The command I executed was : 

erdpy --verbose contract deploy --project=myerc20-c --pem="alice.pem" --gas-limit=30000000 --proxy="https://testnet-api.elrond.com" --outfile="erc20-c.json" --recall-nonce --send.

 

If anyone could help me, I 'd be much obliged

Hello @trictrac,

 

According to the source code of the contract,

https://github.com/ElrondNetwork/sc-examples/blob/master/erc20-c/erc20.c#L85

it seems that it requires an argument (the total supply) at deploy-time (the init function is executed at deploy-time).

You can fix this by providing the argument in the erdpy command, as follows:

... your command ... --arguments 0x0002540be400

Let us know how it goes.

the argument there:

0x0002540be400

represents the supply = 10 000 000 000 in hex.

Thanks a lot for the help, guys. It's a kind of obvious now that you've pointed me in the right direction
