Hi Alexander,
I’m just testing this on my own.
From further testing, the file dffs-command-set_e20ee710c94bda4b8391.js file displays error when uploading it to a 365 doc library but a SP2016 doc library upload works.
Also, when I pasted the code from dffs-command-set_e20ee710c94bda4b8391.js to a Beautify Javascript website, so it’s formatted correctly, the new file uploads to my 365 doc library 100% with no errors.
Dev console error attached.
Brett.
