evOwnerSketchPlane can't figure out a sketch's plane

(At bottom of featurescript is where I've been trying to get it to work)

I made a ridged tab feature that could add a little tab connection for 3dp parts, but when I try to have evOwnerSketchPlane evaluate a sketch's plane that was placed on an inside edge, on the inside of a cylindrical face, instead of on the outside of a cylindrical pin head, it says it cannot resolve (@evOwnerSketchPlane: CANNOT_RESOLVE_PLANE). This situation should be the same except for the faces around the edge, but the edge itself should still be perfectly circular, and planar, so I don't know why it now can't figure it out as I am still directly referencing what created the sketch.

You were querying the sketch outside the loop, so moved it inside and changed your id hierarchy:

for (i = 0; i < size(pinHeadEdge.subqueries); i += 1)
            {
                var sketchPlane = evPlanarEdge(context, { "edge" : qNthElement(pinHeadEdge, i) });

                var slitSketch = newSketchOnPlane(context, id + i + "slitSketch12", {
                        "sketchPlane" : sketchPlane
                    });
                // Create new sketch on each pin edge plane

                var circA = measureDiameter(context, {
                            "entity" : qNthElement(pinHeadEdge, i)
                        }) / meter / 2;
                // Measure pin head diameter

                var tabWidth = (definition.slitDepth / meter / definition.tabFlexMult) / (definition.ridgeSize / meter / 0.000396875);

                var slitWidth = max(definition.ridgeSize * 2 / meter, circA - tabWidth * 2);

                skRectangle(slitSketch, "slitRectangle", {
                            "firstCorner" : vector(-circA - definition.ridgeSize / meter, slitWidth) * meter,
                            "secondCorner" : vector(0, -slitWidth) * meter
                        });

                skSolve(slitSketch);
                // Solve sketch

                opExtrude(context, id + i + "extrude12", {
                            "entities" : qSketchRegion(id + i + "slitSketch12"),
                            "direction" : sketchPlane.normal * -1,
                            "endBound" : BoundingType.BLIND,
                            "endDepth" : definition.slitDepth,
                        });
            }
