Error Message

Known Causes
4 known causesMalformed JSON Data
The JSON data provided is syntactically incorrect or malformed, preventing MySQL from parsing and validating it against any schema.
Schema Constraint Violation
The JSON document is syntactically correct but violates specific rules defined in the column's JSON schema, such as missing required properties or invalid value patterns.
Incorrect Data Types
A value within the JSON data does not match the expected data type specified for its corresponding property in the JSON schema (e.g., providing a string where an integer is required).
Overly Restrictive Schema
The JSON schema definition itself might be too strict or incorrectly designed, leading to valid application data being unintentionally rejected.
