Drill Down not working in Dashboards

[mauricio_cs]

I'm facing a problem with a not working drill field in Safari and Google Chrome neither.

In Safari, when I click this drill field element I'm receiving the message: "The string did not match the expected pattern."

In Google Chrome, when the same drill field is clicked, the message is: "Unexpected end of JSON input".

In this other post, the solution was marked as turning the option LookML Legacy Runtime on, in the Admin -> Legacy resources. 

But I'm still facing the same problem, even with this legacy runtime on.

How can I fix this?
