sway = no got removed with dbf6121ff4a0ff748cf4eab79cd1e1b7cc1e97c3
as mentioned in the commit, you can now emulate the same setting by unsetting SWAYSOCK.
i'm sure everything works as it should internally, but these lines might need to be rewritten https://github.com/artemsen/swayimg/blob/d026cb9d182ca742d3adab67b3fa7ba7db1d3bd6/src/sway.c#L256
would it be ok to just remove the error now since unsetting SWAYSOCK is default behavior on everything except sway? Sway users without SWAYSOCK set might not be aware that they essentially have set sway = no though, which could be an issue. reverting some of dbf6121ff4a0ff748cf4eab79cd1e1b7cc1e97c3 or adding --silent might be preferable.
