I'm following the tutorial : https://microsoftlearning.github.io/advanced-gen-ai/Instructions/04-finetune-model.html

However at the end when I test the data it fails with error :

 File "/opt/miniconda/envs/userenv/lib/python3.8/site-packages/inference_schema/schema_decorators.py", line 341, in _deserialize_input_argument
    raise ValueError("Invalid input data type to parse. Expected: {0} but got {1}".format(
ValueError: Invalid input data type to parse. Expected: <class 'list'> but got <class 'dict'>

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/opt/miniconda/envs/userenv/lib/python3.8/site-packages/azureml_inference_server_http/server/routes.py", line 222, in handle_score
    timed_result = main_blueprint.user_script.invoke_run(request, timeout_ms=config.scoring_timeout)
  File "/opt/miniconda/envs/userenv/lib/python3.8/site-packages/azureml_inference_server_http/server/user_script.py", line 139, in invoke_run
    raise UserScriptException(ex) from ex
azureml_inference_server_http.server.user_script.UserScriptException: Caught an unhandled exception from the user script


The data submitted is direct from the tutorial :

{ "input_data": { "columns": [ "input_string" ], "index": [0, 1, 2, 3, 4], "data": [["Contoso Suites exceeded our expectations with their impeccable service and luxurious amenities."], ["The breathtaking mountain views from our room at Alpine Ski House made our stay truly magical."], ["We had a disappointing experience at Margie's Travel due to the lack of cleanliness and outdated facilities."], ["The cozy fireplace in our room at Alpine Ski House created a warm and inviting atmosphere after a day on the slopes."], ["The rooftop pool at Contoso Suites offered a stunning panoramic view of the city, making our stay unforgettable."]] } }

Can't see any issue unless the tutorial itself contains an error?
