Missing data leads to MethodError

[haberdashPI]

I'm seeing a ~~strange~~ bug ~~that I don't quite understand~~ on AoG 0.6.0:

This code runs successfully

show_decades = (4,5,6,7)
plotdf = subset(plotdf, :decade => ByRow(∈(show_decades)))
plt = mapping(:percent, :mean; color=:dataset, layout=:decade => x -> string("$(10x) - $(10(x+1))")) *
      ((data(subset(plotdf, :measure => ByRow(==("model")))) * 
       mapping(lower=:mean_lower, upper=:mean_upper, group=:measure) *
       visual(LinesFill)) +
      (data(subset(plotdf, :measure => ByRow(==("ground_truth")))) * 
       mapping(group=:measure) *
       visual(Lines, linestyle=:dash)))
save(joinpath(plotdir, "mean_byage_timeline.png"), draw(plt; figure = (; resolution=(1800, 1600))))

But if you change one line:

show_decades = (2,3,4,5,6,7)

Update: you can also change the line to

show_decades = (3,)

This appears to be about the missing value in mean_lower, mean_upper.

It now throws an error:

ERROR: MethodError: no method matching color(::Observable{Any})
