nbconvert with schemdraw not working

[TRiedling]

I use nbconvert with different notebooks and it works.
But when I export a notebook with nbconvert in which I use schemdraw I get the following error:

...
File "/home/torsten/.local/lib/python3.10/site-packages/nbformat/validator.py", line 503, in validate
    raise error
nbformat.validator.NotebookValidationError: data.cells[{data__cells_x}] must be valid exactly by one definition (0 matches found)

Failed validating <unset> in notebook['data']['cells']:

On instance:
<unset>

My notebook:

import schemdraw
import schemdraw.elements as elm
with schemdraw.Drawing() as d:
    d+=elm.Resistor()
    d+=elm.Line().down()
    d+=elm.BatteryCell().left()
    d+=elm.Line().up()

How I use nbconvert:

jupyter nbconvert --to pdf  test.ipynb

I'm using:
Jupyternotebook 6.4.12
Python 3.10.6
on Linux Mint

Hi @TRiedling, thank you for submitting this issue! Is this the only library that you find you have issues with using NbConvert? If so, it is likely that this issue would be better addressed in the schemdraw repo.

Hi @TRiedling, just following up with you on this issue, is this problem still occurring? If you could share whether or not this library is the only library that results in this issue as mentioned would also be helpful.

This issue might also be better addressed in the nbconvert repo.

I am facing the same issue. I do not fully understand what the problem is and the error message is not descriptive enough for me to be able to fix it. Can someone please help?
