Failed to build tree: child link of joint not found

edit

I wrote an xacro file with the UR10 robotic arm, and after checking with check_urdf, I got such an error.

Failed to build tree: child link [laser_link] of joint [laser_joint] not found at line 226 in /build/urdfdom-UJ3kd6/urdfdom-0.4.1/urdf_parser/src/model.cpp ERROR: Model Parsing the xml failed

Here is the content of my XACRO file. Is there something wrong?

<?xml version="1.0"?>
  <robot xmlns:xacro="http://wiki.ros.org/xacro" name="transforrobotdxp" >

     <xacro:ur10_robot prefix="" joint_limited="false"/>
     <link name="world" />
     <joint name="world_joint" type="fixed">
          <parent link="world" />
          <child link = "base_link" />
          <origin xyz="0.0 0.0 0.0" rpy="0.0 0.0 0.0" />
     </joint>
     <joint name="laser_joint" type="fixed">
          <parent link="wrist_3_link" />
          <child link = "laserlink" />

     </joint>

thank you very much!

Here is the laserdxp file.Base_link is defined in the ur10.urdf.xacro file.
