json.decoder.JSONDecodeError

[draew6]

Hi, I am using yfinance daily. Thank you very much for support! But today I received on all scripts I am using this error:
Something changed with new version that is causing this?

Getting same issue now on the yf.download() call, but used it successfully this morning. Didn't make any changes to my version today.

[dennistamyf]

Is experiencing the same problem. Was running my service normally as of last night.

[GuyHersh]

Also same issue, was working fine about an hour ago. I was on an older version of yfinance, same error before and after updating.

[hshi0001]

Same here, worked well 2 hours ago

[daneasterman]

Yep same error for me as well when running any of the history commands, for example: msft.history(period="max")
I'm on this version: yfinance==0.1.59
Thanks for your help in advance!

[ywluohao]

same issue, is yahoo finance updating again...sigh

[D1al-T0ne]

Having the same issue! Tried other versions of yfinance.
Tried pulling historical data with Ticker and Download both come back with same error.

[rubikscube09]

Same issue :( - Started about half an hour ago.

[chandakrishabh]

Also having the same issue!

[shivpalit]

dup:

#363
#691

looks like it's Yahoo server side problem.

[torolearning101]

same same.... can't believe they can't make it more stable.

[hshi0001]

happened before?

[Quantaria]

Same issue this morning. Happened mid-day.

yfinance/yfinance/base.py

Line 157 in 1cc8d96

data = data.json()

data in this line returns something like b'Forbidden'. Agree with @mingwugmail, seems like Yahoo side problem.

[djl0]

for me, adding a user agent fixed the problem:

headers = {'User-Agent': 'Firefox'}
data = self.session.get(url=url, headers=headers, params=params, proxies=proxy)

yfinance/yfinance/base.py

Line 152 in 1cc8d96

data = self.session.get(url=url, params=params, proxies=proxy)

But I'm not sure what the user-agent should be for a project like this, so I'm hesitant to create a PR for this.

Works for me now:

line: 151
headers = {'User-Agent': 'Firefox'}
data = _requests.get(url=url, headers=headers, params=params, proxies=proxy)

@y11z

can you also try add threads=False:

df = pdr.get_data_yahoo(symbol, start=start_date, progress=False, threads=False)

It worked for me as well, on Linux.

@djl0 I think you definitely should create a PR.

Worked for me.

What's the best way to edit the package and implement these changes locally? Would like to try it myself.

[ranaroussi]

Fixed with 0.1.62.

Please upgrade using pip install -U yfinance

[lfelipecid]

headers = {'User-Agent': 'Firefox'}

Worked for me!

[JiaxinLIU0998]

The same issue

Fixed with 0.1.62.

Please upgrade using pip install -U yfinance

It seems that upgrading does not work for me

[ranaroussi]

@JiaxinLIU0998 try:
pip install yfinance -U--no-cache-dir

[goldmonkey21]

Fixed it by installing from git:

pip uninstall yfinance
pip install git+https://github.com/ranaroussi/yfinance.git#egg=yfinance

Works!

[shivpalit]

Anyone know how to fix this issue on Heroku? What should be added to the requirements file?

[ranaroussi]

See issue #764

[jalfgit]

i noticed the fix with the upgrade. anyone seeing adj close column coming through?

[NabanCodes]

pip install -U yfinance worked for me
