Why does not the crafting recipe work?

I'm just making a mod… Again! And the crafting recipe does not work that writes: Missing data 'minecraft: coal' how can I fix this?

Can it be that the "," in line 6 has slipped to line 7?

I'll check it out and then give you feedback.

Unfortunately this can't be, because the "," must be between pattern and key to separate it also would be the "," in line 6 pointless because there's nothing to separate…
