interface error (computing)

[SolExpDB]

There are some smart contract functions that do not have a return value and defining the interface will result in an error. There are also cases where the same function name has a different return value.

I am not following @SolExpDB. Do you think the solidity compiler error is wrong or that the vscode extension has autocompleted or quickfixed in a way that generates a compiler error?

[SolExpDB]

@kanej I think this is a bug in the vscode extension, some functions with the same name and arguments but different return values are not buggy. But there are some functions that give an error

Solidity error 1686 is coming from solc, this issue is part of the Solidity language.
