@LouisGac: I didn't fixed this bug.
I can't reproduce it with error message, but I can see that graph silently fails to load in pdf or Excel file.
So I would try to fix it.

The error does not appear if I turn off the debug mode as it is said in

I guess this happens cause it is a warning so if debug mode is turned off it does not show anything.
