when i click on an attachment that is an image, e.g. a jpeg, a black overlay appears, showing a error symbol, i guess that means an error has happened. I tried some things:
- save the attachment by clicking on the save symbol: works
- copy and past the link url that open the gallery into a new tab: works
- look at error logs: nothing conclusive
- Inspecting the element in the browser, the console shows an exception:
Uncaught TypeError: _super.prototype.expose_onslide is undefined
So my initial conclusion is: there is no problem with the email or the server, as the attachment can be loaded correctly.
I am using egroupware 21.1.20220408 installed via docker compose as suggested.
Has anyone a pointer where to look next?
