Hi,

I am trying to install plugin for logstash.

But whenever I execute `.\logstash-plugin list` to see a list of available plugins. I keep getting bad uri error

```auto

```

How can I resolve this issue.

I am on Windows 10 machine. I have already configured my environment variable with HTTP\_PROXY and HTTPS\_PROXY value

Thanks

The exception is telling you that your proxy value matches neither of these regular expressions:

```

```

Note that those are anchored to start and end of string using \A and \z. Is it possible you have quotes or spaces or something else around the URI?

Hmm... that was indeed the case.  
It has now resolved the issue for me.  
Thanks
