Wildcard in fdiscovery filter, null_pointer_exception

OpenSearch
1

Opensearch v 3.1.0, browser Chrome 138.0.7204.97

In version 3.x of Opensearch, when using a filter based on wildcards in discovery, the search ends with the error “Internal Server Error, null_pointer_exception” Moreover, filters with a regular expression continue to work normally.
In version 2.x, the wildcard worked normally. Tell me where to look to see what broke?
Filter:

{
  "query": {
    "wildcard": {
      "cs_uri_stem": {
        "value": "*mapi*",
        "case_insensitive": true
      }
    }
  }
}

Error:

null_pointer_exception
Cannot invoke “org.apache.lucene.util.automaton.ByteRunAutomaton.step(int, int)” because “runAutomaton” is null

@urfin73 I’m not able to reproduce this. Can you please elaborate if this is something you can reproduce from devTools or only using discovery. Can you provide a sample document maybe? Are you seeing the error only on UI or also in the logs?
