How do you use assert_result?

[batomow]

Im trying to test if a function runs without throwing any errors, but it tells me that i can't use 'is_success' on base nil.

func test_add(
	cfuzzer := Fuzzers.rangei(-100 * cell_size, 100* cell_size), 
	rfuzzer := Fuzzers.rangei(0, cell_size-1)
	): 
	var base_cell = Vector2(cfuzzer.next_value(), cfuzzer.next_value())
	for __ in range(10): 
		var coords = base_cell + Vector2(rfuzzer.next_value(), rfuzzer.next_value())
		var n = Node2D.new()
		n.global_position = coords
		assert_result(hashmap.add(n)).is_success()
		auto_free(n)

Is this not intended for function results ?

Hm, looks like the hashmap.add(n) returns null and the assert_result.is_success() can't handle null values.
You using the Result type as return type on add(n) right?

I will convert this question into a bug issue. #191

Will be fixed by v1.1.2 where is release to day

Thanks for reporting.
