In the front end

A "use typeshade" file never reaches this check with the same mistake: the front end refuses it first, under its own code. This program, compiled at build time, gets:

"use typeshade"

declare const tex: texture_2d_array<f32>
declare const smp: sampler

@fragment
export function main(@location(0) uv: vec2): vec4 {
  return textureSample(tex, smp, uv, 1.5)
}

How to fix it

The registry's hint: a fractional layer literal is a naga compile error in WGSL but silently rounds in GLSL (layer = floor(z + 0.5), so 1.5 reads layer 2) — the backends would diverge; pass an integer, or an i32/u32 node

TS8041 TEXTURE_ARGUMENT

A plain argument of a texture read that the target has no overload for: a coordinate or gradient of the wrong width for the texture's dim or of an element kind the read does not take (a sampled read is by normalised f32, a texel fetch by whole i32/u32 texel), a layer, mip level or sample index that is not an integer or is not a whole number of 0 or more, and a level, bias or depth_ref that is not an f32.
