How can I handle custom errors in Flask JWT authentication?

You can handle custom errors in Flask JWT by creating a custom error handler using Flask's error handling features.

Can you show me an example of a custom error handler?

Sure! You can define a custom error handler like this:

from flask import Flask, jsonify
from flask_jwt_extended import JWTManager, jwt_required

app = Flask(__name__)
jwt = JWTManager(app)

@app.errorhandler(Exception)
def handle_error(e):
    response = jsonify({'message': str(e)})
    response.status_code = 400  # or any other status code
    return response

What kind of errors can I customize?

You can customize errors for expired tokens, invalid tokens, and any other authentication-related issues.

Is there a way to log these errors?

Yes, you can log errors by integrating Python's logging module within your error handler.
