Sending an API query to ZOOMA container returns Error 500 - Initialization of LuceneAnnotationSummarySearchService failed

[uuo118]

I'm testing ZOOMA container with the tag 'stable', although the problem was also true for 'main-44881 image'. When sending the API query, for example requests.get("http://www.localhost:8009/zooma/v2/api/services/annotate?propertyValue=control") the server returns Error 500. Here're the contents of zooma.log

2021-07-26 17:29:04,315 ERROR [http-nio-8080-exec-6] access.Zooma (Zooma.java:682) -
Unexpected search exception [SearchException: Failed to complete a search for 'control' 
(java.lang.IllegalStateException: Initialization of LuceneAnnotationSummarySearchService failed)]

The query runs fine when requesting from the webserver.
