Clear-RabbitMQQueue doesn't work anymore, it throws the exception "Object not found"

[Spamme1]

A couple of days ago a script using the "Clear-RabbitMQQueue" stopped working because now the function throws an exception. From the verbose output it seems that the default virtual host "/" shouldn't be un-escaped in the invoked URL (%2f) but for some unknown reasons now it is un-escaped to "/", and the result is an "Object not found" error.
The output of a PS shell below shows, how the queue "Monitor 1-C347847 Technical" exists in the virtual host "/", but clearing it throws the exception "Object not found".
