I am working in AppDesigner and I create an uiaxes where i simply plot some lines. When the mouse is near the plotted line i get a bunch of errormessages in the command window:
Warning: Error occurred while executing the listener callback for event MouseMove defined for class

The reference object is invalid.

This issue occurs when we try to plot mixed datatypes in UIAxes in R2019a. This has been fixed in R2019b.
Meanwhile for R2019a, you can try a workaround for disabling the errors/warnings.
plot(....) % Your plot command
ax = gca;

I had a similar issue. I was working with uint's. I found if I plotted my data as double, I no longer received the constant warning.
plot(app.UIAxes, xData, double(yData))
