Thanks; you're a lifesaver. I needed -blank_before_header as well to get the DevOps wiki to parse properly, but once I'd looked up space_in_atx_header, that was easy enough to find.
Try with
-f markdown-space_in_atx_header
commonmark doesn't allow headings with no space after #, nor does pandoc with its default settings, but you can disable that extension as above.
