I'm using Logstash 6.8 and am using some updated versions of plugins which have been updated with the command:

`logstash-plugin update logstash-filter-kv logstash-input-s3 logstash-filter-json`

This has worked fine for a long time but since roughly two weeks ago I am now getting this error when trying to run logstash after updating plugins:

```

```

It doesn't seem to be affected by which plugins I update, just updating any will produce this error when I run logstash after updating. Any ideas why and how to fix?

I've tried this on 6.8.2 and 6.8.10 with similar results.  
Thanks!

Looks like this is actually a problem with how I'm launching Logstash, and may not be a problem with Logstash itself.

I'm running it through logstash-filter-verifier. I have raised an issue here with a reproduceable test case: [https://github.com/magnusbaeck/logstash-filter-verifier/issues/84](https://github.com/magnusbaeck/logstash-filter-verifier/issues/84)
