It looks like the program ran into a parsing error. The "invalid character '<' looking for beginning of value" typically points to an unexpected HTML character when expecting JSON. This might be due to the endpoint returning HTML (like a 404, 401 page) instead of expected JSON data. You might want to check the endpoints and ensure they're returning the correct data format.
