The problem is that updatecdt does not allow dynamic field names. But if you add

a!fromJson(substitute(a!toJson({tzqYx62_01_:ri!value}), "tzqYx62_01_", ri!key))

to the above code, even that is possible. It creates a dictionary with a fixed field name and converts it to JSON. Then it replaces the field name in the JSON string to the desired field name and converts it back to an Appian dictionary.
