Mapping error on OH3 Logs

Hello,
recently, analyzing my logs, i noticed that Openhab running on my RPi3 is working fine,
one only message is looping and I do not understand why

[WARN ] [al.profiles.MapTransformationProfile] - Please specify a function and a source format for this Profile in the 'function' and 'sourceFormat' parameters, e.g "translation.map" and "%s". Returning the original state now.

I have one only one .map file for meteo binding named astro.map in the Trasform folder and configured via UI

these is the file content

Some one can help me to understand why ?

maybe it is important to have a look to the UI config…

I set the Item profile like these:

is it correct right?

I would have a close look at all your other Items to see if one has a part-completed MAP profile by accident.

You mean could be one item with MAP flagged but not filname on the field ?

Indeed I discover that If I falg Back NONE and SAVE as the image shown, Openhab do not save and the item comes back with MAP flagged.
I had to remove the links and re-link to solve.

I will report to github req
