missing state name

Error message

missing state name

What it means

Attribute.InternalValidate was called on a nil *Attribute pointer. The exported method guards the nil receiver and returns this error rather than panicking. Internally, a nil entry in a Block's Attributes map is caught earlier with a different message, so this specific message surfaces when callers invoke Attribute.InternalValidate directly on nil.

Solutions

1. Skip nil attribute pointers before calling InternalValidate, or initialize them.
2. When validating a whole Block, prefer Block.InternalValidate which already handles nil map entries.
3. Add a nil check at the call site and surface a clearer upstream error.

Example fix

// before
var attr *configschema.Attribute
if err := attr.InternalValidate("name"); err != nil { return err }
// after
if attr == nil { return fmt.Errorf("name: attribute is nil") }
if err := attr.InternalValidate("name"); err != nil { return err }

// Nil-check attribute pointers before calling InternalValidate.
for name, attr := range block.Attributes {
    if attr == nil {
        return fmt.Errorf("%s: attribute is nil", name)
    }
    if err := attr.InternalValidate(name); err != nil { return err }
}

func attributeNotNil(a *configschema.Attribute) bool { return a != nil }

When it happens

Trigger: Calling `var a *configschema.Attribute; a.InternalValidate("x")`, or passing a nil attribute pointer through code that calls its InternalValidate. Guard at internal_validate.go:132 is `if a == nil`.

Common situations: Provider test helper that iterates attributes without nil-checking; refactoring that leaves an attribute pointer uninitialized before validation.
