Briefly, this error occurs when Elasticsearch is unable to parse the trigger due to an unexpected data type. The trigger type is expected to be a string, but a different data type was found. To resolve this issue, you should check the trigger configuration in your Elasticsearch code. Ensure that the trigger type is correctly defined as a string. If you’re using JSON, make sure the trigger type is enclosed in quotes to denote it as a string. Also, validate your JSON for any syntax errors that might be causing the problem.
