Unit 4: Services in ROS - **Example 4.8**, [rospack] Error: package 'my_custom_srv_msgs_pkg' not found

Hello @TrnDuyNht,

The message is in the package my_custom_srv_msg_pkg, but you are calling the package my_custom_srv_msgs_pkg (note the extra “s” in msgs(s)).

Best,

I modified the command but it still doesn’t work
