            Depending on the platform, the message format in chat logs might not be
            standardized across devices/versions/localization and might change over
            time. Please report issues including your message format via GitHub.

KeyError: 'timestamp_ms'

I dont know how to include format, all i know is that was a .json file from messenger website

Hey @4zjata, thank you for opening this issue! It seems like your export json file does not have a timestamp_ms field. Our parser expects this format:

{
  "messages": [
    {
      "sender_name": "John Doe",
      "timestamp_ms": 1579294140000,
      "content": "Hello Jane!"
    },
    {
      "sender_name": "Jane Doe",
      "timestamp_ms": 1577186580000,
      "content": "Hello John!"
    }
  ]
}

For further investigation, we'd need to have (anonymized) snippet of your json file. You can open the file with any text editor such as VS Code. Would you mind providing this? Thank you! :hugs:
