I see the message:  “Error:  Node 0 is not defined” at the end of your output.  

Do all the named selections (components in MAPDL) have at least one element in them?  Maybe your mesh is too course.

Are you able to run thru the example of manual clustering published in Section 5.7.1 in the Additive Manufacturing (R2022-R2)?
