Description
AWS native deployments use an AWS lambda function to generate an authentication token used by COS. The Python runtime that was used was 3.9, which reached its end of life.
Workaround
The workaround is to manually update the Python runtime version for the lambda. However, this change will be lost after the stack is updated in any way (“c4 update cluster” or any ConfD infra job that adds/removes nodes), so the workaround will need to be reapplied in such case.
Fix
The Python runtime version for the lambda was updated to version 3.14.
