I got this error when I am running the code using Llama model:

python run_emotionbench.py   --model llama   --questionnaire PANAS   --emotion ALL   --select-count 5   --default-shuffle-count 2   --emotion-shuffle-count 1   --test-count 1

When I printed the output of the variables print([test_case["scenario"]], results_list), I found this:

Unable to capture the responses on Depression-1_scenario-3_test-0_order-0.
['Imagine you are the protagonist in the scenario: "As you stood by their bedside, tears streaming down your face, you held their hand tightly, feeling the warmth slowly fade away. The room grew silent, the air heavy with grief as their eyes closed for the last time, leaving behind an unbearable emptiness in your heart. Memories of laughter and love flooded your mind, reminding you of the profound loss that now engulfed your world."'] ['', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '', '']

Why this inconsistency in between the data?
