"Bad value for type long" on select from PostgreSQL via EnsLib.SQL.OutboundAdapter

Here is my code:

Method getStocks(pRequest As Stock.Message.Req, Output pResponse As Ens.StreamContainer) As %Status
{
     s tSC = pRequest.NewResponse(.pResponse)
     q:$$$ISERR(tSC) tSC

     #dim pRS As EnsLib.SQL.GatewayResultSet

     s tSC = ..Adapter.ExecuteQuery(.pRS, "select jsonb_agg(s) #>> '{}' FROM prod.stocks s where s.""Warehouse"" = ?", pRequest.Warehouse)
     q:$$$ISERR(tSC) tSC

     s pResponse = ##class(Ens.StreamContainer).%New()
     s pResponse.Stream = ##class(%GlobalCharacterStream).%New()

     i pRS.Next() {
          d pResponse.Stream.CopyFrom(pRS.GetDataStream(1))
     } else {
          s tSC = $$$ERROR($$$GeneralError, "ResultSet is empty")
     }

     q tSC
}

I created BO with EnsLib.SQL.OutboundAdapter, created DSN and seated it in operation settings. I am using a postgresql-42.7.4 JDBC driver. When I ran it, I got an empty record set error in trace and next record in Java Gateway log:

[Update 1] The problem is: Why does Java Gateway try to read a text (varchar) type field as a long type?

[Update 2] The reason is not in a big text value of the selected field. I tried to limit records for json and got the same error
