GET data-import-profiles/actionProfiles returns 200 response (empty body) when oom

In an Iris HF3 environment, an OOM error was observed in mod-data-import-converter-storage logs when making request to
GET data-import-profiles/actionProfiles?limit=5000&query=%28cql.allRecords%3D1%29%20sortby%20name

Message is logs is as follows:
Observe in log an issue with OOM
19:12:09 [] [] [] [] INFO  LogUtil              org.folio.rest.RestVerticle start  invoking getDataImportProfilesActionProfiles
19:12:12 [] [] [] [] ERROR ?                    Unhandled exception
java.lang.OutOfMemoryError: Java heap space

Although this issue was observed in the logs – response from api call was a HTTP 200 with an empty body (providing no indication that there was an error/issue)
GET data-import-profiles/actionProfiles?limit=5000&query=%28cql.allRecords%3D1%29%20sortby%20name

Would expect it to return a 500 error, rather than a 200
