Mesh.from_json()

I have used Mesh.from_json() for a long time. Today strangely it gives me the following error:

Message: malformed string

Traceback:
line 79, in _convert, “C:\Program Files\Rhino 6\Plug-ins\IronPython\Lib\ast.py”
line 80, in literal_eval, “C:\Program Files\Rhino 6\Plug-ins\IronPython\Lib\ast.py”

My guess is that the compas version in which the .json file was originally created is older than the one where you are trying to load it. Does the problem persist if you try loading the .json file with an older compas?

Hi Rafael. Thanks for the hint! I think that was the problem. It is solved now!

hi,

would you mind filing an issue about this?
although the current version of dealing with json data is preferred, it should not fail on older versions…

thanks
