Datetime/duration format not supported

When one or both data vectors are Datatime or Duration objects, an error is produced.

No figure is generated, the error is:

In this case the code used was:

t = 0:seconds(30):minutes(3);
y = 1:7;

plot(t,y,'DurationTickFormat','mm:ss')
fig2plotly()

An example of plotting a Duration object using MATLAB is found on:
