Root Cause

Misuse of jsonify or returning a response object incorrectly, often due to missing parentheses or using the wrong import.

generic

中文

误用 jsonify 或错误地返回响应对象，通常是由于缺少括号或使用了错误的导入。

Workarounds

  1. 100% success Use jsonify correctly with parentheses 
    from flask import jsonify
return jsonify({'key': 'value'})
  2. 95% success Use a dictionary directly with Flask's response 
    return {'key': 'value'}  # Flask auto-converts dicts to JSON

Dead Ends

Common approaches that don't work:

  1. Returning jsonify without parentheses 90% fail

    jsonify is a function that must be called.

  2. Importing jsonify from the wrong module 80% fail

    Should be from flask import jsonify.
