i use this code

	local parts = {'body_s1', 'body_s2', 'body_s3', 'top_weapon_s1', 'top_weapon_s2',
					'bottom_weapon_s1', 'bottom_weapon_s2', 'bottom_weapon_s3', 'bottom_weapon_s4'}

	for key, val in pairs(parts) do
		func.delete_texture(gui.get_node('box_preview_' .. val), 'preview_delete')
	end

function func.delete_texture(node, name)
	gui.new_texture(name, 0, 0, "rgba", '')
	gui.set_texture(node, name)
	gui.delete_texture(name)
end

how fix this? please

Can you please provide a complete, but small example, where this behavior can be observed?

problem in this line

gui.new_texture(name, 0, 0, "rgba", '')

i can create empty texture
FIX: (#9899 1) ‘Check if there’s a dynamic texture with the same id before creating it’

all code

function func.make_robot_preview(active_option)
	local options = {'body', 'top_weapon', 'bottom_weapon'}
	local parts = {'body_s1', 'body_s2', 'body_s3', 'top_weapon_s1', 'top_weapon_s2',
					'bottom_weapon_s1', 'bottom_weapon_s2', 'bottom_weapon_s3', 'bottom_weapon_s4'}

	for key, val in pairs(parts) do
		func.delete_texture(gui.get_node('box_preview_' .. val), 'preview_delete')
	end

	for key, val in pairs(global_.equip_data.robots[global_.equip_data.robots.active]) do
		
		if helpers.table_value_index(options, key) ~= nil then
			for key_, val_ in pairs(val) do
				
				local node = gui.get_node('box_preview_' .. key .. '_' .. key_)
				gui.set_texture(node, 'ts_' .. key .. '_' .. global_.equip_data.workshop[key][val_.id].icon)
				gui.play_flipbook(node, '1')

			end
		end
	end
end

function func.delete_texture(node, name)
	gui.new_texture(name, 0, 0, "rgba", '')
	gui.set_texture(node, name)
	gui.delete_texture(name)
end

just add more params to function from gui api ))

gui.new_texture(name, 1, 1, "rgb", string.rep(string.char(0x00) .. string.char(0x00) .. string.char(0x00), 1 * 1))

Probably the error was in the texture size being 0
