##[error]RangeError [ERR_CHILD_PROCESS_STDIO_MAXBUFFER]: stdout maxBuffer length exceeded

[logjeferson]

When I run the export for a slightly larger number of wiki pages I receive the buffer limit error message:

System.ArgumentException: Markdown elements in the input are too deeply nested - depth limit exceeded. Input is most likely not sensible or is a very large table.

When I activate the debug I receive the log below:
##[error]RangeError [ERR_CHILD_PROCESS_STDIO_MAXBUFFER]: stdout maxBuffer length exceeded

Below are the complete debug logs:

Typically that means that a table is not well-formatted. Run the converter locally and see what page causes this and then check the tables on that page.
