Just wanted to point out that the property name of credsStore is correct. docker login | Docker Documentation. This is usually an error that happens when the credsStore value config (in this case “desktop”) cannot be retrieved. In my case, the underlying problem was that I installed Docker Desktop but then reinstalled it to use just Docker Engine with Desktop. The credsStore value in ~/.docker/config.json did not update or remove the credsStore value, so it errored properly. If you are not using another credsStore, just remove the value as a whole. Renaming it to credStore may just confuse you later if you ever need to look at it again.
Disclaimer: This happened to me on a Linux install but the same would apply to WSL2 or MacOS. You may not want to try deleting the value for MacOS. It might need to be “osxkeychain”.
