After upgrading to 14.0.0 SchemaError: Expected type 'FieldSet' to be a GraphQLInputType

After upgrading to 14.0.0 getting below error, if anyone face similar issue, please guide me

Caused by: graphql.kickstart.tools.SchemaError: Expected type 'FieldSet' to be a GraphQLInputType, but it wasn't!  Was a type only permitted for object types incorrectly used as an input type, or vice-versa?
