Describe the bug

I downloaded the zip and extracted it.

Now I got this error:

Processing corpus into lines and conversations...

JSONDecodeError: Unterminated string starting at: line 1 column 91 (char 90)

On this line:
lines, conversations = loadLinesAndConversations(os.path.join(corpus, "utterances.jsonl"))

Describe your environment

I just clicked on the Collab Notebook button and ran it

Start with the Chatbot Tutorial linked in the issue and reproduce the failure using its Colab Notebook flow. Inspect the downloaded corpus file utterances.jsonl and the loadLinesAndConversations call where JSONDecodeError occurs. Done means the tutorial can process the corpus past this step without the reported unterminated-string error.
