When using akka.serialize-messages = on together with Phobos it throws errors in the application when trying to fetch the actor hierarchy

[wesselkranenborg]

When I have Phobos 1.1.3 and Petabridge.CMD 0.8.5 I get the following errors when I want to fetch the actor hierarchy via pbm. Also no hierarchy is shown except /user.

Output of the pbm console:

petabridge.cmd (0.8.5.0)
Copyright 2017 - 2021, Petabridge�.

successfully connected to [::ffff:127.0.0.1]:9110
Commands downloaded from server. type help to see what's available
[127.0.0.1:9110] pbm> actor hierarchy
/user

Errors thrown in the application running the actorsystem:

After upgrading to Phobos 1.1.4 this issue also occurs.

Thanks @wesselkranenborg - I'll see about marking these messages as not traceable in Petabridge.Cmd. They probably shouldn't be included TBH since there are a huge number of them and tracing pbm's internal operations probably isn't high on anyone's list
