Hi, I’ve as usually an error when importing from a folder.

Using “rossrv list | grep MyCustomServiceMessage” and “rossrv show path_exam/MyCustomServiceMessage” I can find the service but when I run the .launch it give me the error about “no module named …”

I tried to recompile after deleting build and devel, and also to source devel/setup.bash" in every termin I run the .launch but nothing.

Hi @umberto.severino,
Just to confirm your importing your custom service message using:
from package_name.srv import service_message_name right…?
