    General consensus is that yfinance==0.1.62 or newer fixes the issue. Duplicates -> [yfinance json.decoder.JSONDecodeError](https://stackoverflow.com/q/68328050/15497888), [The same code that used to work is now returning an exception](https://stackoverflow.com/q/68331693/15497888), [When I run this simple file I get this .json error](https://stackoverflow.com/q/68331957/15497888) – Henry Ecker Jul 11 '21 at 18:19
  • This means yfinance is not returning a valid JSON object. – Jishan Shaikh Jul 11 '21 at 18:33
