PostgreSQL Error 2203F: JSON Value Not Scalar
Description
Error 2203F, 'sql json scalar required', indicates that a SQL/JSON function or operator was expecting a single scalar JSON value (e.g., a number, string, boolean, or null) but received a non-scalar value like an array or an object. This typically happens when extracting or manipulating JSON data where the path or operation implicitly expects a primitive type.
Error Message
sql json scalar required
Known Causes
3 known causesIncorrect JSON Path
The SQL/JSON path expression used in a query extracts an array or an object instead of a single scalar value, leading to a type mismatch for the intended operation.
Mismatched Function Usage
A SQL/JSON function designed to operate exclusively on scalar values is applied to a JSON array or object, resulting in a data type conflict.
Non-Scalar Data Input
The JSON data stored in the database column contains arrays or objects in locations where later queries expect simple scalar values, violating data expectations.
