I am trying to add Azure Machine Learning Service function on a streaming job using a pretrained hugging-face sentiment analysis model (cardiffnlp-twitter-roberta-base-sentiment)

While adding the function i am facing this challange:

Function signature
Value cannot be null. Parameter name: source

I have deployed the endpoint for (cardiffnlp-twitter-roberta-base-sentiment) on Azure ML Studio. I am trying to integrate that on Azure Stream job, but getting this error:

Function alias

Subscription:
