when trying to publish a topic in flow in visual edition I get this
[c5691ad38140b1463dccece8] Caught exception of type Flow \ Exception \ WikitextException
for the problem this use the next patch - The patch with MW 1.38.0 and Flow 1.2.0 (74ffd17) 08:41, 26 May 2022 does not work, or you can config the next variable: $wgVirtualRestConfig['modules']['parsoid']['url'] and point to the url access of the rest.php of the wiki.
