Error with ML.NET tutorial on Sentiment Analysis

Question

Hi,

Recently I began using Microsoft Learn' tutorials on ML.NET to learn Machine Learning and building apps using Model Builder. I have started with the analyzing sentiment using Razor Pages tutorial (https://learn.microsoft.com/en-us/dotnet/machine-learning/tutorials/sentiment-analysis-model-builder) but keep running into an error:

String was not recognized as a valid Boolean. on var sentiment = Convert.ToBoolean(prediction.Prediction) ? "Positive" : "Negative"; in Index.cshtml.cs

This is the code snippet I took right from the tutorial article. The code on GitHub for this sample says the same, but I keep running into this error.

Why does this occur and how can I fix this?

Thank you for your help!
