RabbitMQ control plugin (3.2.x) generates Javascript error (TypeError or undefined)

Question

After making changes to the cluster, the following two errors began to be saved on the "Overview" tab on each node of the cluster.

On 3.2.1 Node:

TypeError: Unable to read connection properties undefined

On 3.2.2 Node:

undefined: no template in js / tmpl / login.ejs

In addition, the tabs for connections and channels were empty (although there were definitely connections to the cluster)

The only suggestions on the Internet (which didn't work) were to clear the browser cache.

Errors in the browser console were as follows:

sammy-0.6.0.min.js:
runRoute get # /
404 Not Found get # /
runRoute get # /
