How to extract useful info from "SerializeObject obj"?

[divB]

I have tons of messages like

2020-06-17T23:16:32.770428: [error  ] ECDatabaseAttachment::LoadAttachmentInstance(): no row returned
2020-06-17T23:16:32.770482: [error  ] SerializeObject obj 15191 failed: disk error (80000007)
2020-06-17T23:16:32.770526: [debug  ] gSOAP error on processing request: SOAP_FATAL_ERROR

in my log. That’s super annyoing! How do I find out what 15191 refers to?? I have access to the mysql database. My guess was it’s “hierarchyid” of table “properties” but this doesn’t really make sense.
