Briefly, this error occurs when Elasticsearch is unable to parse a role due to incorrect data type. It expects an object but is receiving a different data type instead. To resolve this issue, you should check the role definition and ensure it is correctly formatted as an object. Also, verify the data type of the input being passed to ensure it matches what Elasticsearch expects. If you’re using a script or application to generate the role, ensure it’s correctly configured to output the correct data type.
