Hey mkab ,
Thanks for reaching out and welcome to the Buttonizer Community 🥳
Good point, we indeed don't ship the .map files as they are meant for debuggin issues (and the client doens't see those errors).
However, we'll alter the code in our next update so it won't search for a .map file on your site.
I'll let you know when that's done! In the meantime, if you have any further questions, make sure to let us know 🙂
