langchain_core.exceptions.OutputParserException when running the steamilt app

[Mazzesy]

When trying out the web_explorer, I get the error below. I have the relevant keys. Did anyone face the same issue?

Traceback (most recent call last):
File "/Users/mn/PycharmProjects/web_explorer/venv/lib/python3.9/site-packages/pydantic/v1/main.py", line 522, in parse_obj
obj = dict(obj)
TypeError: 'int' object is not iterable

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

During handling of the above exception, another exception occurred:
