You create a 5-foot-diameter sphere of fire in an unoccupied space on the ground within range. It lasts for the duration. Any creature that ends its turn within 5 feet of the sphere makes a Dexterity saving throw, taking 2d6 Fire damage on a failed save or half as much damage on a successful one.
As a Bonus Action, you can move the sphere up to 30 feet, rolling it along the ground. If you move the sphere into a creature’s space, that creature makes the save against the sphere, and the sphere stops moving for the turn.
When you move the sphere, you can direct it over barriers up to 5 feet tall and jump it across pits up to 10 feet wide. Flammable objects that aren’t being worn or carried start burning if touched by the sphere, and it sheds Bright Light in a 20-foot radius and Dim Light for an additional 20 feet.
Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 2.

The spell description has this as a Conjuration spell, but the Druid, Sorcerer, and Wizard spell lists in the 2024 PHB list it as an Evocation spell. Was it supposed to be changed to Evocation but the description didn't get updated, or are the spell list entries in error?
That's a good question, did you ever find an answer for it?
No. I'm hoping there will be errata for it at some stage, though.
Errata v1 doesn't include it.
As far as I can tell it is still a conjuration spell, same as in 2014 rules, and as listed in the chapter 9 spell description. Just wrong on the spell lists in the class chapters.
