Indescriptive error on port overlap assertion #28

Closed oatmealine closed 1 year ago

oatmealine commented 1 year ago

There is an assertion set to prevent two servers from using the same port. However, a message is not set, producing a confusing error when the assertion is triggered:

error: attribute 'message' missing

Huh, I thought I would have set a message there, but apparently not!
