TypeError: encoding without a string argument

[joseberlines]

I have a double multindex dataframe, i.e. multindex and multindex in the columns names.
when passing it to pygwalker I get:

File ~/.local/lib/python3.10/site-packages/pygwalker/utils/fname_encodings.py:4, in fname_encode(fname)
      3 def fname_encode(fname: str):
----> 4     return base64.b64encode(bytes(fname, 'utf-8')).decode()

TypeError: encoding without a string argument

Is this because pygwalker does not admit double multindex?

Hello,

I'm not quite sure if this pr solved your problem, but it does avoid some bugs behaving like this in some cases.

To verify this, please try pip install "pygwalker==0.1.4.2.post0" or pip install "git+https://github.com/Kanaries/pygwalker@33-typeerror"
