In the first control point passed by the AGV, two control points are generated on two parallel paths through the script, namely cp1 and cp2, and a new path is generated, whose name is path_in, and path_in connects cp1 and cp2. Add a task sequence through the script, so that the AGV passes through cp1 and cp2 in turn, but after the AGV reaches cp1, it will report an error, and there is no valid path to reach cp2.
