I am running the UI app JAR locally and while the main functions seem to work correctly, the search function seems to be broken. In that typing in a search string is not returning anything (i.e. the left pane gets blank). I debugged that the REST API call (sample below) is returning a blank array [].

There is no firewall or such - the UI is running local to the browser. From the UI output, there is no exception shown. The only variable is that I am using Azure Cosmos DB Mongo API but again on the server side there is no apparent issue. Is there any further logging I can turn on at the Java side to debug this issue further?
