JAVA - Cassandra ERROR - Codec not found for requested operation
I want to get all database's IDs. To to that I have to get all databases, and then I'll getId for each database and add it to the list of strings (id is string). But after all I'm getting error:

Request processing failed; nested exception is com.datastax.driver.core.exceptions.CodecNotFoundException: Codec not found for requested operation: [list java.util.Set]


This is my query at dbrepository:

@Query("SELECT * FROM db_params")
Result getAllDatabases();


And service to get list of IDs...
