Unrecognized JSON log error

[guillaume-gc]

I'm experimenting with this tool, which is amazing! Unfortunately, I'm getting this error:

2024-10-03T15:20:17.838Z	e6ffdb72-1be8-4e9d-90f4-b66850933570	ERROR	Invoke Error 	
{
    "errorType": "Error",
    "errorMessage": "Unrecognized JSON log",
    "stack": [
        "Error: Unrecognized JSON log",
        "    at module.exports.extractDurationFromJSON (/var/task/utils.js:673:11)",
        "    at module.exports.extractDuration (/var/task/utils.js:616:22)",

        "    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)"
    ]
}

Here is some context, with all information redacted:

2024-10-03T15:20:17.837Z	e6ffdb72-1be8-4e9d-90f4-b66850933570	ERROR	Detected invalid JSON line:

            "ResourceType": "REDACTED",

            "CreatedBy": "REDACTED",
            "InternalVersionId": "REDACTED"
        }
    }
}
]}}}

I assume the issue is caused by the ] character?

Here is log that appears to be causing the issue:

                        }
                    }
                }
            ]
        }
    }
}

Here is the Step Functions input, without the payload key:
