Trying to edit my post at https://www.mediawiki.org/wiki/Topic:S350su8j3v2p0e3d#flow-post-s37cemffsn5qh41x

gives an pink error message box:
"Database query error".

Webconsole says:
"[FLOW] " "apiPreHandler returned false" "preview" Array [ Object, Object ] load.php:177

The "load.php:177" links to this highlighted source:
dependencies:[],group:typeof group==='string'?group:null,source:typeof source==='string'?source:'local',state:'registered',skip:typeof skip==='string'?skip:null};if(typeof dependencies==='string'){registry[module].dependencies=[dependencies];}else if(typeof dependencies==='object'||$.isFunction(dependencies)){registry[module].dependencies=dependencies;}},implement:function(module,script,style,msgs){if(typeof module!=='string'){throw new Error('module must be a string, not a '+typeof module);}if(!$.isFunction(script)&&!$.isArray(script)){throw new Error('script must be a function or an array, not a '+typeof script);}if(!$.isPlainObject(style)){throw new Error('style must be an object, not a '+typeof style);}if(!$.isPlainObject(msgs)){throw new Error('msgs must be an object, not a '+typeof msgs);}if(registry[module]===undefined){mw.loader.register(module);}if(registry[module]!==undefined&&registry[module].script!==undefined){throw new Error('module already implemented: '+module);}
