WorldMap not working (getting 'None')

Superset version: 0.17.0

The WorldMap visualization is not working in my installation. For instance, the slice ‘% Rural’ that comes as example does not work. It shows an error bar with ‘None’. And the server prints this backtrace:

2017-03-07 08:26:01,438:INFO:root:SELECT country_code AS country_code, SUM("SP_RUR_TOTL_ZS") AS "sum__SP_RUR_TOTL_ZS", SUM("SP_POP_TOTL") AS "sum__SP_POP_TOTL"

When I try to add a WorldMap with my data I get another different error:

I tried to debug it by myself and found that metrics has an array like [my_var, None], so in the iteration, when it comes to None it failed to valid it as a metric. I tried to filter that in the code but then appeared another error:

I suppose that the problems with the ‘% Rural’ example and my data are differents, but I can’t tell.

Also, I have added a key for the MapBox API, but I think this is irrelevant, as that map doesn’t use it.

Thank you very much.

Update

The error with my own data was my fault, and it seems it has nothing to do with the WorldMap view.

I found that I got the same error (Metric ‘None’ is not valid) but was solved when I updated the Bubble Size field, even if I was not presenting bubbles (show bubbles check box unchecked).

Hi all. I’m getting the same Metric 'None' is not valid error on the WorldMap visualization.

I tried using superset 0.17.4 and 0.17.1. No luck. I tried this viz on my custom dataset, and also tried it on the World Health demo data, by opening the Table and trying to create a new viz. Any ideas?
