Briefly, this error occurs when the ‘random_score’ function in Elasticsearch receives an incorrect data type for the ‘seed’ parameter. The ‘seed’ parameter should be an integer, long, or string, but it has received a different data type. To resolve this issue, you should check the data type of the ‘seed’ parameter in your query and ensure it is either an integer, long, or string. If it’s not, you should convert it to one of these data types before passing it to the ‘random_score’ function.
