Global error handler for any exception

Question

Is there a way to add a global catch-all error handler in which I can change the response to a generic JSON response?

I can\'t use the got_request_exception

Answer 1

Based on Plain (non-HTML) error pages in REST api

I wanted to return json without changing any of my code at all, so I just added the following on the top of my code

@app.errorhandler(500)
def error_500(exception):
    return jsonify({"error": str(exception)}), 500, {'Content-Type': 'application/json'}

@app.errorhandler(400)
def error_400(exception):
    return jsonify({"error": str(exception)}), 400, {'Content-Type': 'application/json'}
