I haven't dug into this too much, but one example that causes it is:
/effect give @e[type=sheep] glowing
If there are sheep around, it gives out:
An unexpected error occured trying to execute that command
But the sheep do indeed glow.
It also happened with a few other commands, but I wasn't able to see a pattern yet.
The log contains this:
