Error bars not being plotted using errorbar()

[xarico10]

For any plot using errorbar(), error bars are not being plotted and a 2D regular plot is showed instead.

For example,

x = 1:10:100;
y = [20 30 45 40 60 65 80 75 95 90];
err = 8*ones(size(y));
errorbar(x,y,err)

fig2plotly();

Expected and generated (https://chart-studio.plotly.com/~xarico10/216/#/) plots:

Therefore, any input argument related to error bars is working either:

x = 1:10:100;
y = [20 30 45 40 60 65 80 75 95 90];
yneg = [1 3 5 3 5 3 6 4 3 3];
ypos = [2 5 3 5 2 5 2 2 5 5];
xneg = [1 3 5 3 5 3 6 4 3 3];
xpos = [2 5 3 5 2 5 2 2 5 5];
errorbar(x,y,yneg,ypos,xneg,xpos,'o')

fig2plotly();

Expected and generated (https://chart-studio.plotly.com/~xarico10/218/#/) plots:

In both cases, the following warning message is printed:

Unrecognized field name "UData".
We had trouble parsing the errorbar object.
This trace might not render properly.
