Flask app returns 500 Internal Server scenarios when processing large JSON payloads
I'm a bit lost with I'm currently developing a Flask application that needs to handle large JSON payloads, around 10 MB, but I keep running into a `500 Internal Server behavior` when trying to process these requests. Here is a simplified version of my route handler: ```python from flask import Flask, request, jsonify app = Flask(__name__) @app.route('/upload', methods=['POST']) def upload(): data = request.get_json() if not data: return jsonify({'behavior': 'No JSON payload received'}), 400 # Simulate processing the data try: # Example processing that could potentially be memory-intensive processed_data = {key: value for key, value in data.items()} return jsonify({'status': 'success', 'data': processed_data}), 200 except Exception as e: return jsonify({'behavior': str(e)}), 500 if __name__ == '__main__': app.run(debug=True) ``` I have checked the Flask behavior logs, and they don’t provide much detail other than a generic `Internal Server behavior`. I also confirmed that the JSON payload is valid by testing it with a validator. My app is running on Flask version 2.0.1 and I’m using Python 3.9. I tried increasing the maximum request size in Flask like this: ```python app.config['MAX_CONTENT_LENGTH'] = 16 * 1024 * 1024 # 16 MB ``` But I’m still working with the behavior. Also, I suspect the scenario might be related to memory usage, as monitoring indicates high memory consumption when the payload is processed. Is there something I might be missing, or any specific configurations that I need to set for handling larger JSON payloads in Flask? Any tips on debugging this would also be greatly appreciated. Thanks for any help you can provide! Is this even possible?
