Getting jsonschema jsonschema.exceptions.SchemaError: Schema is not of type 'object', 'boolean',

I am writing a python program for validating json schema with sample JSON and I am using a package called jsonschema for JSON validation. When I run my code I am getting the error. It is showing that there is some is some issue in certain segment of JSON schema.But, I can’t make out what exactly the error means "jsonschema.exceptions.SchemaError:[Schema] is not of type ‘object’, ‘boolean’ " Below is the Python code:-

 # import jsonSchema_validate
 # from jsonSchema_validate import validate
from jsonschema import validate
