How can I handle errors in Flask microservices?

You can handle errors in Flask microservices by using error handlers, logging, and returning appropriate HTTP status codes.

Can you show me an example of an error handler?

Sure! You can define an error handler like this:

@app.errorhandler(404)
def not_found(error):
    return {'message': 'Resource not found'}, 404

What about logging errors?

You can use Python's built-in logging module to log errors. For example:

import logging
logging.basicConfig(level=logging.ERROR)

How do I return custom error messages?

You can return custom error messages by modifying the response in your error handler. For instance:

@app.errorhandler(500)
def internal_error(error):
    return {'message': 'Internal server error occurred'}, 500
