@app.errorhandler() cannot be used in blueprint when debug=False

[mengshun2022]

I want to customize an error type in Flask, and then use @app.errorhandler() in the main program to capture it. Then, I define a function raise_error to actively throw this exception. When debug=True is enabled at runtime, both the main and blueprint routes can be used normally in the interface function. However, when debug=False, only the main route can be used, and the blueprint route cannot capture it and reports a program error,I hope someone can help me take a look
There are two files in total(mains.py,aaa.py)

#python mains.py
from flask import jsonify, Flask
from typing import Union
app = Flask(__name__)

class CustomError(Exception):
    def __init__(self, message, status_code=500):
        try:
            self.message = message.__dict__
        except Exception as e:
            self.message = message
        self.status_code = status_code

def raise_error(msg: Union[dict, str], status: Union[int, str] = 500):
    raise CustomError(msg, status_code=status)

@app.route("/")
def home():
    raise_error("this is error")
    return {}

from aaa import router
app.register_blueprint(router)

@app.errorhandler(CustomError)
def handle_custom_exception(error: CustomError):
    response = jsonify({"code": error.status_code, "data": error.message})
    response.status = 20
    return response

if __name__ == "__main__":
    # app.run(host="0.0.0.0", port=7788, debug=True) #can in blueprint
    app.run(host="0.0.0.0", port=7788, debug=False)  # cannot in blueprint

#python aaa.py
from flask import Blueprint, jsonify

router = Blueprint("aaa", __name__, url_prefix="/aaa")

@router.get("/")
def aaa():
    from mains import raise_error
    print("is runing")
    raise_error("this is eror in blueprint")
    return jsonify({"data": "in blueprint"})
