MySQL Error 3982: Invalid User Attribute JSON Format
Description
This error occurs when attempting to create or modify a MySQL user with an `ATTRIBUTE` clause, but the provided attribute value is not a syntactically correct JSON object. MySQL requires user attributes to be valid JSON to store structured metadata associated with the user account.
Error Message
The user attribute must be a valid JSON object
Known Causes
3 known causesIncorrect JSON Syntax
The provided user attribute string contains syntax errors, such as unmatched braces, missing commas, or improperly quoted keys/values, preventing it from being parsed as valid JSON.
Non-JSON String Provided
The user attribute was supplied as a plain string, number, or boolean literal instead of a properly formatted JSON object, which requires curly braces and key-value pairs.
Invalid JSON Type (Array/Scalar)
While technically valid JSON, the attribute was provided as a JSON array (`[]`) or a scalar value (e.g., `"string"`, `123`) instead of the required JSON object (`{}`).
