I see.
I am also worried a bit.
BUT I used to see them alot when using odrive about a year ago. Maybe they are just not as smooth in handling API timeouts as rclone is.
Currently I am thinking/hoping that another run will just pick them up, since the paths do not seem that long to me (in my case)
If so there is still the possibility to use another way to download missing files, since odrive is nice enough to print the paths accordingly.
since I already have about 50% of my 15TB moved to gdrive I am not that worried. I would have guessed that it would have affected more files/paths if that was the case. we will see in a few hours. 
@Saviq keep me updated.
