Blender2MSFS2 bones animation exportation issue

[d5turbi]

Hi,

When I export an object containing an animation with bones, the compilation fails and the error log indicates:
How can I correct this problem?

A proposed solution was to add the following lines below the while frame <= end_frame line:

if type (frame) is float
frame = int(frame)

Unfortunately, this solution does not work.

thank you in advance for your help
