Taquito default entrypoint not found

Question

I have deployed a smart contract on carthagenet.

The contract only has a single entry point.

Taquito is not able to find that single entry point. I tried both default and root methods and it doesn't work.

const op = await contract.methods.default(contractAddress).send()
const op = await contract.methods.root(contractAddress).send()

Error message

contract.methods.default is not a function
contract.methods.root is not a function

Answer 1

The contract you point to takes a single parameter of type address. Thus, as you write, it only has the default entrypoint. In taquito, the main entry point can be call through contract.methods.main. So your call should be:

contract.methods.main(contractAddress).send()

Answer 2

As the name main was a bit confusing, it was renamed from main to default in the latest version of Taquito (version v7.0.0-beta).

This is a breaking change for implementations that use the main method for calling the default entrypoint of a contract.

Before version 7:

contract.methods.main(contractAddress).send()

Since version 7:

contract.methods.default(contractAddress).send()

More details can be found on the upgrading guide of Taquito.
