[SOLVED] "Could not transform" error

Evening All,

I`m seeing the following error on openhab log:

2018-05-08 22:09:22.272 [WARN ] [rm.AbstractFileTransformationService] - Could not transform '-' with the file 'en.map' : Target value not found in map for '-'

Any idea how to clear it?

Add the following line to your en.map file

-=NULL

Thanks Vincent. Problem solved.

Happy to help
Please mark the thread as solved, thanks
