I have python 3.8.10 and yfinance 0.1.63 installed. I try to import quotes of a value and it returns the error

JSONDecodeError: Expecting value: line 1 column 1 (char 0) when trying to download data from Yahoo Finance

How can i solve this problem. I will appreciate help

I am facing the same error right now.

I am also facing this issue. The response from the api request session.get is 'Forbidden'

[brianhaines]

Resolved after updating. Run this:
pip install yfinance --upgrade --no-cache-dir

I am still having the JSON error after the upgrade. Please help!

[super6liu]

Adding requests_cache session cache worked for me.

[hansiniupadhyay]

@super6liu Can you please share your code that you have added ?

[byteatwork]

Besides upgrade to the latest version of yfinance. You can also consider upgrade library requests to the latest where there is a fix on this particular error message [https://github.com/psf/requests/pull/5856]

That code was recently released in the Requests 2.27.0 release. The latest version is 2.27.1 as of now. Perhaps updating Requests would solve this.
