Change Details

Since a few days ago, mapframe dynamic maps don't reliably work. On the page [[ https://ru.wikipedia.org/wiki/%D0%9F%D0%B8%D0%B7%D0%B0%D0%BD%D1%81%D0%BA%D0%B0%D1%8F_%D0%B1%D0%B0%D1%88%D0%BD%D1%8F | ru:Пизанская башня ]] I get the error ``` Failed to load resource: the server responded with a status of 400 () ``` The resource in question is https://maps.wikimedia.org/geoline?getgeojson=1&ids=Q39054 and it returns ``` "headers is not defined" ``` An other kind of error is on [[ https://fr.wikipedia.org/wiki/Foire_de_Li%C3%A8ge | fr:Foire de Liège ]]: ``` load.php?debug=false&lang=fr&modules=jquery|mediawiki.page.gallery&skin=vector&version=03l1ewh:51 jQuery.Deferred exception: Cannot set property 'dataGroup' of undefined TypeError: Cannot set property 'dataGroup' of undefined at ExternalGroup.<anonymous> (<anonymous>:29:929) at Function.each (https://fr.wikipedia.org/w/load.php?debug=false&lang=fr&modules=jquery%7Cmediawiki.page.gallery&skin=vector&version=03l1ewh:4:868) at <anonymous>:29:656 at mightThrow (https://fr.wikipedia.org/w/load.php?debug=false&lang=fr&modules=jquery%7Cmediawiki.page.gallery&skin=vector&version=03l1ewh:48:856) at process (https://fr.wikipedia.org/w/load.php?debug=false&lang=fr&modules=jquery%7Cmediawiki.page.gallery&skin=vector&version=03l1ewh:49:516) undefined ``` These errors are temporary because now a few minutes later both work again.
