Can not load goroslib/Msg

[Beril-1]

Hello!

When I am trying to do ros echo for some of the msg types, specifically for "/goal" of an action, this error appears:
"ERROR: Cannot load message class for [goroslib/Msg]. Are your messages built?"
Eventually, this is creating a debugging issue. How I can solve it? Thank you.

Cheers,
Beril.

Hello, ros echo needs the exact message definition of a topic to decode it. It must be compiled and installed on the OS with catkin.
Is your action definition part of the standard library or is it a custom one?
Did you compile and install the .action file with catikin?
Can you post both the .action file and the Go struct of your action?
