Error: Invalid number of parameters for "initialize". Got 2 expected 0!

Please correct me if I am wrong. As below shows, This error was caused by there's two initialize() functions and the test case was calling the one with 0 parameters.

And it can be fixed by renaming it e.g. rename initialize to initialise.

Hi @leckylao! I’m sorry that you had this issue.

We have been able to reproduce this issue by following these steps:

Thanks so much for reporting it! The workaround is to change the call to initialize to specify the function being called:

    //counter.initialize(value, { from: owner });
    counter.methods['initialize(uint256)'](value, { from: owner });

Thank you @abcoathup, that works.
