vault 1.7 token create failed, local node not active but active cluster node not found

I can confirm this behavior. From what I saw, it looks like some moments are necessary to settle down the HA status of the vault cluster after unsealing it even with a single node cluster.

Here is an output from the unseal command and as we can see "n/a" is recorded for HA Cluster status and there is no cluster address either.

+ vault operator unseal Lp0QKU6ts/9Eydb/A3s3DUs5qcyzmxfpDI5M4jfmhY8=
Key Value

Seal Type shamir

HA Cluster n/a

With the status above, `token create` can fail by missing active cluster node.

++ vault token create -ttl=10m -format json
Error creating token: Error making API request.

Here is the expected status after some time for the record.

$ vault status

A quick trick would be something like the following before executing `token create`.

until vault status -format json | jq -r --exit-status .leader_cluster_address; do
    sleep 1
done
