<![CDATA[Unable to upload manifest V3 "world" was unexpected in add-ons management panel]]>Hi,
I'm unable to upload an manifest V3 update.

I get the error

manifest.json is invalid -> Additional properties are not allowed ("world") was unexpected.

'world' is a standard manifest V3 property. Installing the extension manually via drag & drop works w/o problems.

Also works for Chrome/Edge/Firefox in their stores w/o problems

Thank you
Tobias

It seems only the validation is broken cuz I have the same issue, but opera support it, I can use my extension in developpeur mode
