essentials_categorystring nullable

Category override used by the essentials pack. The essentials_category key may be present with a string value, present and null, or absent entirely:

  • V1 nodes: essentials_category is omitted when the node class doesn't define an ESSENTIALS_CATEGORY attribute, and null if the attribute is explicitly set to None.
  • V3 nodes (comfy_api.latest.io): essentials_category is always present, and null for nodes whose Schema doesn't populate it.
