MySQL Error 3165: Invalid JSON Array Path
Description
Error 3165 occurs in MySQL when a JSON path expression attempts to access a specific element within a JSON array, but the provided path is malformed or does not correctly point to an individual 'cell' within that array. This typically happens during operations that extract or modify data within JSON documents using functions like `JSON_EXTRACT`, `JSON_SET`, or `JSON_REPLACE`.
Error Message
A path expression is not a path to a cell in an array.
Known Causes
4 known causesIncorrect Array Indexing
Using an invalid, non-integer, or out-of-bounds index when attempting to access an element within a JSON array using path expressions like `$[0]` or `$[1]`.
Path Targets Non-Array Element
The specified JSON path resolves to a non-array value (e.g., a scalar, object, or null) at a point where an array element was expected by the operation.
Misunderstood JSON Structure
The query assumes a JSON array structure at a particular path, but the actual JSON document holds an object or a scalar value at that location instead.
Malformed Path Syntax
The JSON path expression itself contains a syntax error, preventing MySQL from correctly identifying the target as an array cell.
