🐛 Describe the bug

When I try to fill a quantization, my code causes an error:
TypeError: expected str, bytes or os.PathLike object, not NoneType

It was fixed in master branch yesterday. You can install SG from git to have the latest changes or wait for next release of SG which should happen somewhere next week.
