@jsmith-bdai and @ooctipus would be great to get some quick eyes on that as #2556 breaks the raycaster camera

[jtigue-bdai]

LGTM sorry about the break.

The changes looks good to me, thank you Pascal for catching that.
On the second thought, it seems like we are getting quite some bugs recently because of user omits env_ids may being slice or sequence, or (maybe) None. After merge in this, maybe we should consider adding test for env_ids type for our mdps. Or if dealing with so many cases for env_ids may be too unwieldy for customer(even ourself), maybe we should consider not exposing None or slice, but give then Sequence only. Happy to discuss more on this @jtigue-bdai @Mayankm96

thanks for catching the fix! it does seem like the ID flexibilities have been hitting us in a couple of places recently, we should consider the design for Newton as well and see what makes sense to support.

I agree @kellyguo11 and @ooctipus, we should introduce tests for the cases.
