runtime error in offline trajectory generation #121

I occasionally get the following kind of error that crashed my program. Any idea what may cause this?

Hey @nkashiri, I've committed a fix for this to the master branch. Can you confirm that it solves your issue?

nkashiri commented 2 years ago

Thanks @pantor As it is not a repeatable error (it happens sometimes), I cannot confirm immediately. I'll update this issue

Feel free to reopen if the fix doesn't work for you.
