owner_address is required upon calling contract's decimals()

[yenkhoon]

tronWeb.contract(contractConfig.abi, contractConfig.contractAddress).decimals().call()

hit this error:

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "class java.security.InvalidParameterException : owner_address isn't set.".]

This is just a read operation why does the owner_address has to be set?

[yanghang8612]

For historical reasons, the contract interaction interfaces are designed so that the owner_address is a required field, even though it doesn't play any substantial role for view-type methods.

You can pass 0x000000000000000000000000000000000000000000000000 or T9yD14Nj9j7xAB4dbGeiX9h8unkKHxuWwb to populate this field.
