6.507 Error ModManager.cpp:1758: Error while loading recipe prototype "power-house" (recipe): IngredientPrototype must be a dictionary and contain "type" property.
Shorthand format using an array is no longer supported in property tree at ROOT.recipe.power-house.ingredients[0]

Here's a quick fix. This is in data-updates.lua.

data:extend({{
name = 'power-house',
type = 'recipe',
enabled = false,
ingredients = {
{type="item", name="mechanical-parts-01", amount=1},
{type="item", name="intermetallics", amount=8},
{type="item", name="electronic-circuit", amount=25},
{type="item", name="small-parts-01", amount=15},
{type="item", name="steel-plate", amount=20},
{type="item", name="lead-plate", amount=30}
},
results = {
{type="item", name="power-house", amount=1}
},
energy_required = 0.5
}})

This is indeed the fix for the error, but I am personally not getting the error in the first place. I could fix it, but I would personally like to understand why it is even happening for you.
You are on Factorio 2.0.54 right? Maybe you can post a full mod list?

Pushed the update anyway, even though I don't understand why it is working for me
