Crash when building Custom Structure

[NeddoFreddo]

When I try to build the structure, I get this error:

The log says the exact same thing as the game.

I checked map.lua and this is the related paragraph.

function Map:CanDeployRecipeAtPoint(pt, recipe, rot)
    return self:IsPassableAtPoint(pt:Get())
        and (recipe.testfn == nil or recipe.testfn(pt, rot))
        and self:IsDeployPointClear(pt, nil, recipe.min_spacing or 3.2)
end

Which doesn't really explain to me why it's crashing.

My prefab.lua:

    Asset("ANIM", "anim/musicprototyper1.zip"),

Any help would be appreciated.

I don't have a clue about what is wrong, but does the crash happen when :

- you build the structure (click on "build" button)

- you place it on ground

?
Also, does the same crash happen if you try to spawn the structure with console commande ? ( c_spawn("musicprototyper1") )

It could help define when the crash happen.

@NeddoFreddo, this doesn't look right:

return Prefab( "common/musicprototyper1", fn, assets, prefabs),
        MakePlacer( "common/musicprototyper1_placer", "musicprototyper1", "musicprototyper1", "idle" ) 

You're either missing a parenthesis, or have an extra comma there.

return Prefab("common/objects/musicprototyper1", fn, assets, prefabs),

MakePlacer( "common/musicprototyper1_placer", "musicprototyper1", "musicprototyper1", "idle" )

Your missing the objects search path near the end, I got the code from my mod if you want to take a look for side by side comparison. I was a bit lazy when it came to making the hammer function. Also putting:  inst.entity:SetPristine() may help in fn() just before TheWorld.ismastersim. Idk why that pristine function is needed but it does cause problems down the road without it.

Here's one of my structure code feel free to do a comparison:

P.S I have another structure in my dust mod named dust_resurrection if you need another example.
