MySQL Error 3157: JSON Depth Exceeded
Description
This error indicates that a JSON document you are attempting to insert or manipulate in MySQL has exceeded the database's internal limit for nesting depth. MySQL imposes a maximum depth to prevent excessive memory usage and ensure efficient processing of JSON data.
Error Message
The JSON document exceeds the maximum depth.
Known Causes
3 known causesExcessive JSON Nesting
The JSON data being processed contains too many levels of nested objects or arrays, exceeding MySQL's configurable depth limit (typically 32).
Recursive Data Serialization
An application attempts to serialize a complex object with recursive references into a JSON document, leading to an infinitely or excessively deep structure.
Auto-Generated Complex JSON
Data generated by external tools or libraries might inadvertently produce JSON documents with a depth that exceeds MySQL's maximum allowed nesting.
