Problems filling 3D texture in compute shader

Question

I’m trying to fill an empty Texture3D in a compute shader
Here is a minimal reproduction of the GDscript code i’m using:

extends Node

const IMAGE_FORMAT: Image.Format = Image.FORMAT_R8

@export_file("*.glsl") var shader_path: String
@export var resolution: int = 0

var resoult: Texture3D

func _ready() -> void:
	resoult = compute(resolution)

func compute(res: int) -> Texture3D:
	var rd: RenderingDevice = RenderingServer.create_local_rendering_device()
	
	var shader_file: RDShaderFile = load(shader_path)
	var shader_spirv: RDShaderSPIRV = shader_file.get_spirv()
	var shader: RID = rd.shader_create_from_spirv(shader_spirv)
	
	#OUTPUT TEXTURE
	var tex_format := RDTextureFormat.new()
	
	tex_format.format = RenderingDevice.DATA_FORMAT_R8_UNORM
	
	tex_format.width = res
	tex_format.height = res
	tex_format.depth = res
	
	tex_format.usage_bits = \
	RenderingDevice.TEXTURE_USAGE_SAMPLING_BIT +\
	RenderingDevice.TEXTURE_USAGE_STORAGE_BIT +\
	RenderingDevice.TEXTURE_USAGE_CAN_COPY_FROM_BIT
	
	tex_format.texture_type = RenderingDevice.TEXTURE_TYPE_3D
	
	var texture: RID = rd.texture_create(tex_format, RDTextureView.new())
	
	var uniform_out := RDUniform.new()
	uniform_out.uniform_type = RenderingDevice.UNIFORM_TYPE_IMAGE
	uniform_out.binding = 0
	uniform_out.add_id(texture)
	
	
	
	var uniform_set: RID = rd.uniform_set_create([uniform_out], shader, 0)
	
	var pipeline: RID = rd.compute_pipeline_create(shader)
	
	var compute_list: int = rd.compute_list_begin()
	rd.compute_list_bind_compute_pipeline(compute_list, pipeline)
	rd.compute_list_bind_uniform_set(compute_list, uniform_set, 0)
	var workgroups: int = ceili(res/8.0)
	rd.compute_list_dispatch(compute_list, workgroups, workgroups, workgroups)
	rd.compute_list_end()
	
	rd.submit()
	rd.sync()
	
	
	var data: Array[Image] = RenderingServer.texture_3d_get(texture)
	
	print(rd.texture_is_valid(texture))
	
	var tex := ImageTexture3D.new()
	tex.create(IMAGE_FORMAT, res, res, res, false, data)
	
	rd.free_rid(shader)
	rd.free_rid(texture)
	rd.free_rid(uniform_set)
	rd.free_rid(pipeline)
	
	rd.free()
	
	return tex

And the compute shader:

#[compute]
#version 450

layout(local_size_x = 8, local_size_y = 8, local_size_z = 8) in;

layout(r8, binding = 0) restrict uniform image3D output_texture;

void main() {
    imageStore(output_texture, ivec3(gl_GlobalInvocationID), vec4(0.5,0.0,0.0,0.0));
}

But when I run the project, it returns the following error:

E 0:00:01:140 node.gd:61 @ compute(): Parameter “tex” is null.
<C++ Source> servers/rendering/renderer_rd/storage_rd/texture_storage.cpp:1514 @ texture_3d_get()
node.gd:61 @ compute()
node.gd:11 @ _ready()

and a nothing is returned.
It seems like it’s impossible for it to retrieve the data from the texture, but I have no idea at all why it isn’t working
How can I fix this?
Thanks in advance

Ok I got it to work
I just used texture2Dlayered instead of texture3D in the compute shader and then converted it back to texture3D
