How do I add annotations?

[pdavis68]

I'm trying to add annotations as per this example.

But it balks in the "Type: 'Annot'"

No overload matches this call.
The last overload gave the following error.
Argument of type '{ Type: string; Subtype: string; Open: boolean; Name: string; Rect: number[]; Contents: PDFString; Color: RGB; }' is
not assignable to parameter of type 'LiteralArray'.
Object literal may only specify known properties, and 'Type' does not exist in type 'LiteralArray'.

153 Type: 'Annot',

I'm assuming the way this is done has changed?

This is my code:

    const annotation = doc.context.obj({
      Type: 'Annot',
      Subtype: 'Text',
      Open: true, 
      Name: name, 
      Rect: this.getRect(field.boundingRegions), 
      Contents: PDFString.of(this.getFieldValue(field)), 
      Color: rgb(0,  0,  0), 
    });
    doc.context.register(annotation);
