ERROR: Cell attributes must be a dictionary.

[felixcremer]

I am trying to preview a quarto notebook which used to work before, but now I get the following error. I suspect that I wronly formatted something, but it would be nice, if I could get an indicator where to look for my mistake.

This is the error I got and attached is the quarto file that throws the error. Renamed to a .txt because of githubs upload filter.

Perhaps line 130,

#| eval:false

The missing space between : and false might be a problem for the YAML parser perhaps.

Which version did this notebook work fine on, and which version are you on now?

[felixcremer]

Thanks, yes, that was the line that made problems. I don't know whether it was the exact version that worked or whether I introduced the formatting error somehow between the successful and failing run.

The failing run was on QuartoNotebookRunner 0.9.0.
