Zaiming (Stone) Shi 9316690c29 fix(schema): binary string for default values A lot of the string value fields had default value defined in schema as list-string rather than binary-string. This caused the generated schema dump (in JSON format) to have raw_default field as an integer array.		2023-02-21 09:09:51 +01:00
