Hi, we’d like to utilize vault to generate service account tokens for k8s clusters. At first it was working OK but we encountered failure some time (30min ~ 50min) after configuring the k8s secret engines. Error message from vault server only shows “unauthorized” and no more valuable information. We want to see what bearer tokens vault pass to k8s api-server. Can someone tell us how can we do it? Is there any debug mode that can help us?
