lua error message when rendering blog post

[werkstattcodes]

Hello,

I am moving some posts from my distill blog to quarto. In several instances, I get the following error message when rendering the posts with quarto:

Error running filter C:/Users/Roland/AppData/Local/Programs/Quarto/share/filters/layout/layout.lua:
...ata\Local\Programs\Quarto\share\pandoc\datadir\_json.lua:167: bad 'for' initial value (number expected, got nil)
stack traceback:
        ...ata\Local\Programs\Quarto\share\pandoc\datadir\_json.lua:381: in function '_json.decode'
        ...ta/Local/Programs/Quarto/share/filters/layout/layout.lua:3754: in function 'parseLayoutWidths'
        ...ta/Local/Programs/Quarto/share/filters/layout/layout.lua:4419: in function 'layoutCells'
        ...ta/Local/Programs/Quarto/share/filters/layout/layout.lua:4240: in function <...ta/Local/Programs/Quarto/share/filters/layout/layout.lua:4233>
ERROR: unexpected character 'l' at line 1 col 1

Any idea what this could be due to? I can run all cells (Quarto: Run All Cells) without the problem. The code of one such post would be available here.

Any hint most welcome. Many thanks!

PS: I think I saw somewhere a function which allows rendering a document only up to a specific point (in contrast to the entire document). If anyone knows what I mean, it would help me to isolate the issue to i.e. a specific chunk. Thanks again.

Would you mind trying to isolate which part of your document causes that issue? It's hard for us to do it because the document you share has a number of data files.

Solved the problem. Keeping 'layout' in the chunk header instead of changing it to 'column:' triggered the error. Many thanks nevertheless for your reply.

Thanks for this. I have been scratching my head for ages trying to figure this out! You are a genius!
