Incorrect padding error when Splunk Cloud is getting input from an Azure table

[sujitdmello]

My Azure table is not getting sucked into Splunk.

I see the following error every 5 minutes (that's the interval that I setup) :

Old thread, but we had the same issue. Support suggested that it could be related to invalid characters in the base64 encoding. Our Azure user noticed a plus sign (+) in the access key for the azure account, and thought maybe that was the reason based on this article

https://www.8bitavenue.com/2018/02/base64-encoding-in-python/

he created a new access key with no invalid characters and it is working now. I'm not positive that was the problem/solution, but thought I'd at least share it out here as an option for people to try.
