Did an upgrade from Splunk ES 6.1.1 to 6.6.2 and now any dashboard that uses the Downsampled Line Chart viz fails to load with a "Failed to load source for Downsampled Line Chart visualization. "
In fact, any of the visualiztions below the "More" header when selecting a chart type (includes histogram, box plot, 3D scatter plot.) Has anyone run into such an issue after upgrading?
