ValueError: cannot convert float NaN to integer

See original GitHub issue

Describe the bug I attached the file that I cannot export and it took me 3 hours to find the problem because the script does not indicate the object that creates problems.  but it generates a generic report, this is something that is not a big problem with a few objects but with my file with over 1700 objects it was difficult to locate the object.

I got an answer, from the developers, and with this command executed in the python console in object mode C.active_object.data.validate(verbose=True) I was able to solve the problem by identifying the problem and eliminating the vertices which are actually very few (14) Maybe this could be useful to create a solution in these cases.
