Azure Data Lake Input Traceback error

[LasseBK]

I'm trying to connect to a csv-file in a Azure container. It seems to work find to connect as it finds the csv-file, which I can chose. But then I get this traceback error. Anyone who knows what to do?

Hello @LasseBK 

I apologize for the delayed response!

In the error message, this is stated:

File "C:\Users\lbkr\AppData\Roaming\Alteryx\Engine/../Tools\azure_data_lake_input_v2.0.0\AyxProxySession.py", line 4, in <module>
import requests
ModuleNotFoundError: No module named 'requests'

It looks like you may be missing part of your Azure data lake input tools. As @ArtApa  recommended, I would make sure you are on the most recent version of the Azure connector, and see if updating resolves the error.

If you are still having trouble please reply back with an updated error message!

Thanks,

TrevorS

Hi, I have a similar issue with the v.2.0.0. 

(i have tried to delete and re-download the Data lake connector)

I get the following error message after i first login to the storage account and choose the file (have tried with connecting to both csv's and Json files.)

In the past the tool and connection have work, I needed to re-install my computer and after that I started to get this issue. I have tried to use the latest version v.2.0.1 as well, but there I get an error with "missing token" (apperently there is an issue with the connection credentials for the latest version)

Anyone have any idea how to resolve my issue?

Any updates on this? I have the same issue, old version not working due to this error, new version of tool not working because of authentication error in the latest version of the tool.

Hi Guys,

I've opened a case in Alteryx Support and I'm waiting for a solution too.

Thanks.

Whats the update on this? @TrevorS

I faced a similar issue and the error message is somewhat vague in my experience. What fixed for me (with version 2021.3.2) was just to reduce the overall memory (RAM) required for the activities involved in the Alteryx pipeline.

So, please check if below steps help resolve the issue:
1. Remove every other activity from the Alteryx Workflow window other than this particular activity which is of immediate concern

2. Running the Alteryx workflow a higher RAM system.
