API reports a problem with master but gives no reason

[utdrmac]

GUI shows no issues. But API does. There's no reasoning in the API on what the problem is. mysql1 in this context is current master.

@utdrmac please update to latest release where this is resolved.

[utdrmac]

@shlomi-noach I'm on the latest release 3.0.14 as reported by /web/status

[utdrmac]

This is a different issue from #756.

[shlomi-noach]

Can you please clarify what problem is reported by the API? I can't see it in the original comment.

[utdrmac]

Hey Shlomi. There is no problem. That's the issue. If you look in the GUI, there is no error/problem. If you query the /api/problems then you get 1 server back. But there is no problem. So if there is no problem, why is the API reporting the server? Shouldn't the API report back an empty array?

[utdrmac]

Let me rephrase that. if there is in fact an error, you cannot tell via the API. But I configured this simple M/SS setup, and I know there's no errors. There are no errors in GUI. Yet, the API keeps returning back 1 server (the master) has having some problem, but you cannot tell what that problem is.

[shlomi-noach]

@utdrmac got it! Sorry I'm in need of coffee.

Right. #793 has been merged 21 days ago, and I haven't released since then.
If you use master you should see a Problems field in the JSON output.
