Hi guys, For one of my ab test I'm not able to Query the results. I got this error. My source is Mixpanel

Hmm. Haven't seen that error before. Can you send me the query result tables in that modal so I can reproduce it?

Hi Jeremy. It's weird... the error has changed. Look at it.
Copy code
|   	| dimension  	| variation  	| users  	| metrics  	|
|---	|---	|---	|---	|---	|
| 0  	| ""  	| "control"  	| 426  	| [{"metric":"met_19g614kx7koqy6","users":426,"count":0,"mean":null,"stddev":null},{"metric":"met_19g614kx7knbhj","users":426,"count":56,"mean":1,"stddev":0}]  	|
| 1  	| ""  	| "finance_partner_is_ace"  	| 406  	| [{"metric":"met_19g614kx7koqy6","users":406,"count":0,"mean":null,"stddev":null},{"metric":"met_19g614kx7knbhj","users":406,"count":29,"mean":1,"stddev":0}]  	|
Here is the query result

ok, thanks. I'm guessing it has to do with the mean and stddev being null for one of the metrics.

Ok. Is that the expected behavior?

no, I'm working on coercing those values to always be numbers before sending them to our stats engine.

Pushing out a fix now. Will be live in about 10 minutes
I don't think this will fix the original error you saw, which I'm guessing can happen really early in a test when there is very little data. If it happens again, can you let me know and send me the query results?
