I'm on 39794d5 on develop (post 6.1) and I can easily reproduce on my laptop a problem with an SQL query in GuestbookResponseServiceBean.

jakarta.servlet.ServletException: Exception [EclipseLink-4002] (Eclipse Persistence Services - 4.0.1.payara-p1.v202304041433): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: org.postgresql.util.PSQLException: ERROR: trailing junk after numeric literal at or near "3a"
  Position: 69
Error Code: 0
Call: select count(o.id) from GuestbookResponse  o  where o.dataset_id  = 3and eventtype != 'AccessRequest'
Query: DataReadQuery(sql="select count(o.id) from GuestbookResponse  o  where o.dataset_id  = 3and eventtype != 'AccessRequest'")

Steps to reproduce:

• Create a dataset via API. I've been using mvn test -Dtest=FilesIT#testAddTinyFile.
• Log in and look for the draft
• Click on the draft
• BOOM, the error above

Screenshots:

Here's the fix we need (an extra space on line 931:

- query = em.createNativeQuery("select count(o.id) from GuestbookResponse o where o.dataset_id = " + datasetId+ "and eventtype != '" + GuestbookResponse.ACCESS_REQUEST +"'");
+ query = em.createNativeQuery("select count(o.id) from GuestbookResponse o where o.dataset_id = " + datasetId+ " and eventtype != '" + GuestbookResponse.ACCESS_REQUEST +"'");

I thought I'd be able to reproduce the problem on https://beta.dataverse.org which is running the same commit, but I can't seem to. I'm using Docker locally but it shouldn't matter. The SQL statment definitely needs a space. In my example, dataset id 3 is being glommed onto and as 3and.
