TacoKit @GuessSchema Not working

[Anonymous]

Hi Everyone,

For quite some time now i have tried to create a Schema via @GueSchema  annotation is listed in the documentation  to no avail, i have tried with almost every version of Tacokit.  here is my  configuration . NB this Method is inside a service class as stated in the Documentation.

@DiscoverSchema
public Schema getSchema(@Option GuessSchemmaDataSet guessSchemmaDataSet){

    return  factory.newSchemaBuilder(Schema.Type.RECORD)
            .withEntry(factory.newEntryBuilder().withName("ResponseContent").withType(Schema.Type.LONG).build()).build();
}

  And below is the error i get. when i click on guesschema in studio. Is any one experiencing this issue? or am i doing something wrong?
