Hi Jose, This feels like a bug. Any chance you can make a runnable example that triggers this error? Please use one of the sample datasets at yt-project.org/data or if that’s not possible one of your own datasets, which you can share with us using the yt curldrop (see docs.hub.yt). Once we have a way to reproduce the error, please go ahead and file an issue about this on yt’s github so we don’t lose track.

Hello yt users,
I have tried to save a clump dataset but I'm getting the following error:

*fn=master_clump.save_as_dataset(fields=["cell_mass", "total","x","y","z","velocity_x","velocity_y","velocity_z"])* *print(fn)*
*...*
*Error*
