[jupytext] TypeError: 'coroutine' object is not subscriptable

JupyterLab

Hello,
After installing jupytext package on my JupyterLab server, when I try to create a notebook, I got the following error.
Do I miss something in the configuration?

Traceback (most recent call last):

How did you install jupytext?

Yes, I’ve installed jupytext with mamba install jupytext
jupytext 1.16.3 pyhd8ed1ab_0 conda-forge

Hmmm. Your version is known to be an issue. See here:

“We use asyncio.iscoroutinefunction to determine whether the current contents manager is sync or async (#1260)”

Even though the error there doesn’t match yours, I suspect since ‘coroutine’ is involved in yours, that it is related. Try downgrading to 1.16.2 like the original post there says?

Thank you very much for your quick answer, it works with jupytext 1.16.2.
