    Hi joakimfenno ,

     

    1. Ensure Proper JSON Formatting: Verify that the JSON data being sent from your Python script is correctly formatted. Each message should be a valid JSON object. If sending multiple objects, ensure they are either encapsulated in an array or separated by new lines if sending line-separated objects.[{}]

    2. Validate JSON Before Sending: Use a JSON validation tool to ensure that the JSON data is valid before sending it to the EventStream. This can help catch any formatting issues upfront.

    3. Review Kafka Producer Configuration: Ensure that your Kafka producer in the Python script is configured to send data as a string that represents a valid JSON object or objects. You might need to serialize your data to a JSON string if not already doing so.

    4. Escape Special Characters: In Python, you can use the `json.dumps()` function to serialize your data into a valid JSON format. This function will automatically escape special characters like double quotes. json.dumps() in Python - GeeksforGeeks
