full_lifecycle example error when scoring the model

[xavierBizoux]

Hi, I followed the example full_lifecycle on Viya Stable 2024.05.
After publishing the model to MAS, I try to score the model using the following code (coming from the example):

Select the first row of testing data

x = X_test.iloc[0, :]

Call the published module and score the record

result = module_lm.predict(x)
result

When executing, I get the following error message.

During handling of the above exception, another exception occurred:

KeyError: 'file'

Knowing that I get a HTTP 500 error, I'm not 100% sure if the problem is my environment configuration or with sasctl.
