Hi Christophe,

I'm sorry to follow up again, but I get an error with my large md file

The filter fails with the error

  attempt to concatenate a nil value (field 'text')

The error doesn't mention where the failure happens or what text is causing
the problem.  If you have any advice re how to get more information from
pandoc or lua I would very much appreciate it.

I entirely understand if you don't have time to look at this of course.

best regards,

'ö-Dzin
