Briefly, this error occurs when Elasticsearch expects a specific setting to be either a string or a string array, but it receives a different data type. This could be due to incorrect data input or a configuration error. To resolve this issue, you should first check the data type of the value you’re trying to input. Ensure it matches with what Elasticsearch expects – either a single string or an array of strings. If the data type is correct, check your configuration settings to ensure they are properly set up.
