Same issue here as well.
The sample code of Action Client has this issue:

{
	"resource": "file:///home/user/ros2_ws/src/my_action_client/src/action_client.cpp",
	"owner": "_generated_diagnostic_collection_name_#134d74ae-9837-4f8f-b1b8-45d70d5fccf3",
	"code": "fatal_too_many_errors",
	"severity": 1,
	"message": "Too many errors emitted, stopping now",
	"source": "clang",
	"startLineNumber": 0,
	"startColumn": 0,
	"endLineNumber": 0,
	"endColumn": 0
}

I thought i can ignore this error since It compiles correctly.
But its not finished cleanly as the instruction says though the robot moved as we exepcted.
And when i check ps, it still processing:

Not sure if it is because of this error.
Could you have a look? @staff

I just found this report:

Not exactly the expected execution action client Example 6.2.2 ros basics c++

Hello there, Can somebody explain me why the Example 6.2.2 of the ros2 basics in5 days (c++) doesn’t end cleanly alone like in the example? It seems that the execution of the condition around the spin doesn’t work. Can somebody explain it to me please? Thank you in advance while (!action_client->is_goal_done()) { executor.spin(); } my shell user:~/ros2_ws$ ros2 launch my_action_client action_client.launch.py [INFO] [launch]: All log files can be found below /home/user/.ros/log/202…

So this problem (the process doesnt finish cleanly) is fine now.
But still, the clang error exists.

Hi @reiko.iwamoto,

I’m happy that your code runs nicely.

Related to the clang error, this is just a false alarm that we indeed have to fix. But if the program compiles correctly, you can just ignore those clang-related errors for the moment.
