Trying to aquire a lock on a key/value pair with a non existent session id returns a 500

When I call PUT /v1/kv/whateverkey?acquire= I get a 500 with "Invalid session"

This seems more like a 404 me or probably a 400 since the key doesn't need to exist. I think it would be great if this behaviour would be documented on https://www.consul.io/docs/agent/http/kv.html.

Best,

Start by reproducing PUT /v1/kv/whateverkey?acquire= and trace the Consul HTTP KV endpoint handling for the invalid session response. Check the KV API documentation at consul.io/docs/agent/http/kv.html. Done means the endpoint returns an appropriate client error instead of 500 and documents the behavior.
