We’re confronted with an error message. This error message shall be saved within the $Error Variable.
However, wait a minute, what sort of error is it?
Now let’s clear this error.
What about different error classes? Try this command.

The explanation on this case is an exception of RemoteTransporting.
We will look at the assertion that causes the error or exception in additional element.
