`groupedbar` fails to add error bars with plotly backend

[drelatgithub]

I want to add error bars to a grouped bar chart using groupedbar function using the following line.

groupedbar(rand(3,2); yerror=rand(3,2))

When I use the gr() backend, things work okay, as shown in the screenshot.


However, if I use the plotly() backend, an error is displayed and no plot is produced.

Is it a bug, or is there anything I should do to make it work? Thank you!

I just found a similar issue #439, where groupedbar fails with plotly backend. However, the errors reported are different, and I cannot reproduce the error in #439, so I don't think this is a duplicate.

I can confirm I'm seeing this error as well. @BeastyBlacksmith do you have any idea why this error might be backend-specific?

[BeastyBlacksmith]

It seems this comes from groupedbar setting a fillrange for the yerror:

julia> groupedbar(rand(3,1); yerror=rand(3,1))[1][3][:fillrange]
1-element Vector{Int64}:
 0

which doesn't make too much sense and is not handled in the plotly backend.

Compare with bar:

julia> bar(rand(3,1); yerror=rand(3,1))[1][3][:fillrange] # returns nothing
