When voting on a poll, all users of my instance get a 500 server error.
There’s an error in the logs:

I’m on the recent versions of the software:
[discourse](https://github.com/discourse/discourse.git) 23b75d8a2b
[docker\_manager](https://github.com/discourse/docker_manager.git) e5ff940
[discourse-chat-integration](https://github.com/discourse/discourse-chat-integration) 693c7e9
styleguide 23b75d8a
What can I do to troubleshoot it?

Can you reproduce it in a brand new post? Can you repro on meta? What is the Poll markup?

Repro on meta (leave out the `min` attribute)

The error message for the test poll above is now
`param is missing or the value is empty: options Did you mean? action post_id controller poll_name`
which is a really confusing error.

Can you provide me with the reproduction step? I can’t seem to get the error which you mentioned above.

O icic this is a different bug because you’re not allowed to vote on a poll without selecting any options.
