loading configuration issue

[Jskarie]

version 0.0.73 introduced an issue

this fails with True/False variables.

I have setting "use_metakey": False,
which triggers the error
malformed node or string on line 1: <ast.Name object at 0x7fe137201c50>

authenticationsdk/core/MerchantConfiguration.py line 617
self.logger.info("Mconfig > " + str(ast.literal_eval(json.dumps(details_copy))))

reverting to 0.0.72 fixes the issue
