Hello everyone, I am trying to create a feature script that let me select a plane and put this sketch. This is what I have so far but it still creates an error.

FeatureScript 2815;
import(path : "onshape/std/geometry.fs", version : "2815.0");

annotation { "Feature Type Name" : "Rail Profile" }
export const railProfile = defineFeature(function(context is Context, id is Id, definition is map)
precondition
{
// ----- Plane selector -----
annotation {
"Name" : "Sketch Plane",
"Filter" : EntityType.PLANE || EntityType.FACE
}
definition.plane is Query;

    // ----- Dimensions -----
    annotation { "Name" : "Vertical (0.052)" }
    isLength(definition.vert1);

    annotation { "Name" : "Offset from left (2)" }
    isLength(definition.offsetX);

    annotation { "Name" : "Drop height (4.5)" }
    isLength(definition.dropHeight);

    annotation { "Name" : "Lower vertical (1.948)" }
    isLength(definition.lowerVert);

    annotation { "Name" : "Lower horizontal (3)" }
    isLength(definition.lowerHoriz);

    annotation { "Name" : "Lower rise (1)" }
    isLength(definition.lowerRise);

    annotation { "Name" : "Bottom Offset (3.75)" }
    isLength(definition.bottomOffset);
})

{
// ================================
// Create sketch
// ================================
var sketch = newSketch(context, id + "sketch", {
"sketchPlane" : definition.plane
});

// =====================================
// Build geometry relative to origin
// =====================================

// Starting reference point (top-left corner)
const start = vector(0 * inch, 0 * inch);

// Vertical small segment
const p1 = start;
const p2 = start - vector(0, definition.vert1);

// Horizontal to the right (2 in)
const p3 = p2 + vector(definition.offsetX, 0);

// Vertical drop (4.5)
const p4 = p3 - vector(0, definition.dropHeight);

// Diagonal corner
const p5 = p4 - vector(definition.lowerHoriz, definition.lowerVert);

// Small lower vertical
const p6 = p5 - vector(0, definition.lowerRise);

// Lower horizontal
const p7 = p6 + vector(definition.lowerHoriz, 0);

// Bottom offset downward
const p8 = p7 - vector(0, definition.bottomOffset);

// =====================================
// Add line segments
// =====================================
skLineSegment(sketch, "seg1", { "start" : p1, "end" : p2 });
skLineSegment(sketch, "seg2", { "start" : p2, "end" : p3 });
skLineSegment(sketch, "seg3", { "start" : p3, "end" : p4 });
skLineSegment(sketch, "seg4", { "start" : p4, "end" : p5 });
skLineSegment(sketch, "seg5", { "start" : p5, "end" : p6 });
skLineSegment(sketch, "seg6", { "start" : p6, "end" : p7 });
skLineSegment(sketch, "seg7", { "start" : p7, "end" : p8 });

skSolve(sketch);
