Many ROS messages don't work

[nouaim]

None of these topics have a message working correctly:
/angle4th_topic
/gripper_topic
/joint_states
/position_write_topic

I find only this one working properly:
rostopic info /joint_states

rosmsg show sensor_msgs/JointState
std_msgs/Header header
uint32 seq
time stamp
string frame_id
string[] name
float64[] position
float64[] velocity
float64[] effort
