Featurescript fails when using EvBoundingBox?

Hello all,

I'm currently trying to write a script which evaluates the bounding boxes of a given set of parts, and then prints the vertices to the featurescript terminal. However, when I attempt to do this, it breaks and throws a Precondition of evBox3d failed (arg.topology is Query) error. I have added my code below. I'm sure it's a simple syntax thing, but I'm having a hard time finding relevant information online. Any help is greatly appreciated!

<br>FeatureScript 626;<br>import(path : "onshape/std/geometry.fs", version : "626.0");<br><br>annotation { "Feature Type Name" : "Name Parts" }<br>export const NameParts = defineFeature(function(context is Context, id is Id, definition is map)<br>&nbsp;&nbsp;&nbsp; precondition<br>&nbsp;&nbsp;&nbsp; {<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; annotation { "Name" : "Parts", "Filter" : EntityType.BODY, "MaxNumberOfPicks" : 100000 }<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; definition.bodies is Query;<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // Define the parameters of the feature type<br>&nbsp;&nbsp;&nbsp; }<br>&nbsp;&nbsp;&nbsp; {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (var parts in definition.bodies) {<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // define bounding box<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; const boundingBox is Box3d = evBox3d(context, {<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; "topology" : parts ,<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; });<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; println(boundingBox.minCorner);<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; println(boundingBox.mazCorner);<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // assign names<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; println(" this is the list of parts" );<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br>&nbsp;&nbsp;&nbsp; });<br><br><br>
