Refresh Token Expiry

[smpa01]

@peggysue @gbrueckl 

I have been runing batch jobs and the token is getting expired ~60/75 min.

// header
<CIMultiDictProxy('Content-Length': '104', 'Content-Type': 'application/json; charset=utf-8', 'X-PowerBI-Error-Info': 'TokenExpired', 'Strict-Transport-Security': 'max-age=31536000; includeSubDomains', 'X-Frame-Options': 'deny', 'X-Content-Type-Options': 'nosniff', 'Access-Control-Expose-Headers': 'RequestId,X-PowerBI-Error-Info', 'RequestId': 'f098269c-d1b1-473f-86ae-3da25c0b6555', 'Date': 'Tue, 08 Oct 2024 17:15:34 GMT')>

I tried this but this is not consistent. I desparately need the bacth job to run without getting terminated in between and without needing me to babysit.

from datetime import datetime, timezone
import pytz
import requests


def current_hour ():
    current_time = datetime.now(pytz.timezone('America/Toronto'))
    hour = current_time.hour
    text_hour = str(hour)
    return text_hour

token = notebookutils.credentials.getToken('pbi')  

service_call = requests.get(uri, headers={"authorization": "Bearer " + token,"VariableHeader": current_hour()}) 

Thank you in advance

HI @smpa01,

Perhaps you can try to modify the session timeout of the notebook, you can click on the left-bottom session icon to open session information panel.

@v-shex-msft  Thanks for this and I will take this out on a spin and let u know.

1 question though - Assuming it works, if I am running batchJob.ipynb with the scheduler at nth hour every day, how can I ensure that it runs with the same custom session timeout (e.g. 90 min) everyday? Asked differently, is the same custom session timeout value applies to the notebook on each run and ca different notebooks have different custom session timeout values ?

HI @smpa01,

You can open the workspace setting to modify the spark session timeout.

In addition, you can also consider to use high concurrency mode to running your notebook:

please give me few days to test it out.

HI @smpa01,

Sure, you can feel free post here if the above not helps.

@v-shex-msft  if the notebook is run on a schedule, the token expiry still happens. But if I run the notebook is run from while inside it, then the token does not expire.

I want to run the notebook on a schedule.

HI @smpa01,

As you said, it seems like these setting does not enable when you setting schreuder on it. Have you tried to use high concurrency mode to processing your notebook, it should allow to use more resource on it.

Unfortunately nothing is working, on scheduled job , the token is getting expired around 63-66 min mark (with 90 min timeout session default). I am also not sure if you can defualt a notebook to run with a HC mode. I can only turn on HC mode when inside it.

It is probably because, if I follow this , I get

{
    "token_type": "Bearer",
    "expires_in": 3599,
    "ext_expires_in": 3599,
    "access_token": "loremIpsum"
}

How can I refresh this token or get access to a reresh token that can be used to API calls nearing 60 min mark

Hi @smpa01,

When do you create the Bearer token and do you re-use the Bearer token over multiple notebook sessions? If you do, you may retrieve the Bearer token in every session instead, so you are less likely to exceed the 1h limit of the Bearer token.
