No signature of method: static net.filebot.media.MediaDetection.detectMovie() is applicable for argument types
Posted: 29 Aug 2026, 16:22
I'm suddenly experiencing an error when I fetch artwork/subs with CLI (MacOS Terminal):
I've used the following CLI successfully for several years:
Below is my sysinfo, media are on local Synology NAS (I replaced my actual name with "myname" below):
In trying to resolve this, I deleted my Filebot cache with the following CLI:
I updated Filebot and all Brew casks using CLI (successfully). I searched forums to find similar errors but none seemed to apply. Sorry if I missed a solution that would apply.
The error (top) seems to only happen with media folders that are new, which do not yet have any "poster.jpg" files. If I remove an offending folder, the CLI for fetching artwork will proceed beyond where the error occurred previously. However, when the process reaches a folder that is relatively new without a "poster.jpg" file, the error reoccurs and stops the fetch.
FWIW, I rename media on Windows 11 using scripts that you (RedNoah) and Kim helped me to develop. Those scripts work perfectly and they have for years. The errors only occur when I'm fetching new artwork using MacOS Terminal CLI (which also has worked perfectly for years, until recently.)
Pleaes advise, and thank you.
