pdata.AttributeValue.IsNil() always returns false

[hossain-rayhan]

So, the problem is, I want to write a unit_test for checking if pdata.AttributeValue.IsNil() but I can't.

I tried to use attributeMap.InsertNull("key") and the func NewAttributeValueNull() to create a Nil pdata.AttributeValue but they didn't work. Every-time I call pdata.AttributeValue.IsNil() it returns false. I feel something is wrong with these set of functions. I tried the following two ways. None of them worked to assign a Nil AttributeValue in a pdata.AttributeMap.

Example-1:

        attributeMap := pdata.NewAttributeMap()
	attributeMap.InsertNull("ClusterName")

	if v, ok := attributeMap.Get("ClusterName"); ok {
		if v.IsNil() {
			fmt.Println("Nil Assigned") // Never comes here
		} else {
			fmt.Println("Not Nil")
		}
	}

Example-2:

        attributeMap := pdata.NewAttributeMap()
	attributeMap.InitEmptyWithCapacity(1)
        attributeMap.Insert("ClusterName", pdata.NewAttributeValueNull())

	if v, ok := attributeMap.Get("ClusterName"); ok {
		if v.IsNil() {
			fmt.Println("Nil Assigned") // Never comes here
		} else {
			fmt.Println("Not Nil")
		}
	}
