I am unable to upload a picture in my instance.

My browser says (in F12 console of firefox):

    
SyntaxError client.js:2:1170023
    hw https://лемми.опенсорс.рус/static/0799f19b/js/client.js:2

the file starts with

    
/*! For license information please see client.js.LICENSE.txt */
(()=>{var e,t,n,r,o={45850:(e,t,n)=>{"use strict";n.d(t,

and DeepSeek says that e,t,n,r,o should be separated by spaces, i.e. e, t, n, r, o

The lemmy.ml instance adds that image without problems.
