Task 23 and 24 get "java.util.NoSuchElementException: None.get" observation

[sofyc]

When runnning the inference for task 23 or 24, sometimes the observation, free look and inventory will be "java.util.NoSuchElementException: None.get".

This is likely to happen when you first focus on something and then take some actions.

Here is one example:

"8": {
        "episodeIdx": 8,
        "history": {
            "history": [
