We have someone who will look into this and get back to you.

The readme is out of sync with the official documentation here: https://cloud.ibm.com/docs/cloud-object-storage?topic=cloud-object-storage-python#python-credentials. We will update this.

[IBMeric]

We have resolved this issue with the release of 2.11.0. Can you verify and close this ticket?

[powellquiring]

In the readme:

This did not get me to anything useful https://cloud.ibm.com/docs/services/cloud-object-storage/iam/service-credentials.html

[pjamison-coursera]

I am having a similar issue, just installed 2.11.0 today. Here is the function which seems to be causing the issue

[IBMeric]

Thanks for pointing this out. The COS documentation is going through an overhaul, and that seems to be affecting our readme. I'm going to have an internal discussion to see how to more permanently fix these discrepancies.

[avinash1IBM]

This issue has been fixed in the latest release. Can you please close this issue

[IBMalok]

Closing since the fix was already provided.
