ros2 interface show throw exception "InvalidResourceName"

Question

I have customized some messages. After compiling and source, when I use the ros2 interface show command to view the message definition, it throws the following exception:

Error processing '// generated from rosidl_adapter/resource/msg.idl.em' of 'interfaces/Gps': '//'
Traceback (most recent call last):
  File "/opt/ros/humble/install/bin/ros2", line 33, in <module>

    raise InvalidResourceName(type_string)
rosidl_adapter.parser.InvalidResourceName: //

But if I link the generated ws/install/interfaces/share/interfaces/sensor/Gps.msg file to ws/install/interfaces/share/interfaces/msg directory, it works fine.

Alternatively, moving ws/src/interfaces/msg/sensor/Gps.msg to ws/src/interfaces/msg/ directory and rebuild also works.

Here is the directory structure of my custom message repository:

.
├── CMakeLists.txt
├── msg
│   └── sensor
│       ├── Gps.msg
└── package.xml
