v2.0.0 - BREAKING

• Objects parsed as multiple arguments, should now only be passed as a JSON object in 1 argument.

before

["function","prop1","prop2"]

const verifiedArgs = await Helpers.checkArgs<{ prop1: string, prop2: string }>(args, Yup.object()
            .shape({
                prop1: Yup.string().required(),
                prop2: Yup.string().required(),
            }));

after

["function","{\"prop1\":\"prop1\",\"prop2\":\"prop2\"}"]

const verifiedArgs = await Helpers.checkArgs<{ prop1: string, prop2: string }>(args[0], Yup.object()
            .shape({
                prop1: Yup.string().required(),
                prop2: Yup.string().required(),
            }));
