Errors when trying to install any extension

Having some trouble installing my first extension. I saw the backup extension and it sounded pretty cool, so I tried it, only to be greeted by this:

Any ideas what I’m doing wrong?

What is your mac version and Docker Desktop version? It worked on my macOS Monterey, Docker Desktop 4.12 without configuring any path as it mentioned in the error message.

I can verify this version of Docker Desktop (4.12.0) for Windows also. When Docker Desktop goes to 4.13.0 or above, installation of any extension fails. This issue seems to persist even in the latest version for Docker Desktop. As long as the extension has not been modified recently, it should still install properly under 4.12.0 (you can see what happens for the “Resource usage” extension, for example, that cannot be installed under 4.12.0 because it got updated in 11/2022). Anyway, if you need to download 4.12.0, you can get it from the following URL - Docker Desktop release notes | Docker Documentation . Thanks

Sorry, forgot to mention the latest version of Docker Desktop. It is 4.15.0. Thanks.
