I don't know this code, so apologies if this is not the right thing to do, but if you change classes/classe_damage.lua line 2974 from

to

seems to avoid the error and not break anything obvious.

(based on v8.2.0.7167 from curse)

The SpellId's for all my actions seems to be 0.

If i nil check like you said, details is not putting out errors anymore, but my damage is not attributed anymore.

For example i did 291 Damage in one fight, but only the spells of my pet are listed (71 damage).

So the only thing working for me is the overall list, spell info is currently completly broken for me. Its not even showing Auto-Shot
