Smart contract error not returned

[ezhkovskii]

The smart contract has a function
function _checkOwner() internal view virtual {
require(owner() == _msgSender(), "Ownable: caller is not the owner");
}

I expect the SDK to return an error "caller is not the owner" if user != owner, but If there was an error in the smart contract, it is not returned.
abi_parser.parse_output(fn_name, output) function returns empty result.
status in transaction = 16 - RevertInstruction.

How can I read an error from a smart contract?

cause when error only string message return ,use sample code:
if str(status) is not '0':
outputbody = output[10:] #去掉0x[func_sig]共10个字符
errmsg = decode_single("(string)", decode_hex(outputbody))
