hiWhen I read the attached gmsh mesh using DMPlexCreateFromFile(), I get the following error:

/impls/plex/plexcreate.cThis mesh was created using the meshio Python library (https://github.com/nschloe/meshio).
Gmsh itself seems to think it is valid. What is PETSc's problem with it?It appears to be complaining about the $EndElements line not matching properly, but it looks ok to me.
