An error when using restartworkchain

[nim-hrkn]

Maybe it is because I use still aiida __version__='1.6.9', but an error occurs after all the calculations are successfully finished when using restartworkchain.

A sample script is in sample/restart.py in
https://github.com/nim-hrkn/aiida-dataframe.

The error occurs when

_OUTPUT_DF = True

which outputs FrameData, but no error when

_OUTPUT_DF = False

which doesn't output FrameData.

The Error messages are

I use aiida-lammps for development and still use AiiDA v1.x.

Hi @nim-hrkn,

sorry for the long silence. I just published a new release, including a bug fix that could address your problem.
Could you try to install version 0.1.2 of the package and tell me if that fixes your problem?

[janssenhenning]

Should be fixed with #12 and #5 (your sample script runs without error on my machine now). I'll close the issue for now.

Feel free to reopen if you have more problems related to this
