Error with running flexible search query

[former_member740946]

Hi everyone,

when i run the following flexible search query:

select * from {media}

i get an Error with this message:

ERROR [ hybrisHTTP8 ] [ ConnectionImpl ] transaction of unbinding connection 67(-) has not been ended - will rollback automatically

WARN [ hybrisHTTP8 ] [DefaultHandlerExceptionResolver] Resolved [ org.springframework.http.converter.HttpMessageNotWritableException: Could not write JSON: (was java.lang.NullPointerException); nested exception is com.fasterxml.jackson.databind.JsonMappingException: (was java.lang.NullPointerException) (through reference chain: de.hybris.platform.hac.data.dto.SqlSearchResultData["resultCount"])]

It would be great if anyone tell me why it occurs

Thank you
