Hello @WeepsDanky! I'm here to help you with bug reports, answer your questions, and assist you as you wait for a human maintainer. Let's work together to resolve any issues you may be experiencing.

The issue with the Iteration node not displaying a description might be related to the defaultValue or the checkValid function in the nodeDefault configuration. To resolve this, ensure that the description field is properly set and handled within the Iteration node's configuration. Here is a possible modification to include a description:

const nodeDefault: NodeDefault<IterationNodeType> = {
  defaultValue: {
    start_node_id: '',
    iterator_selector: [],
    output_selector: [],
    description: '', // Add this line to include a description field
  },
  getAvailablePrevNodes(isChatMode: boolean) {
    const nodes = isChatMode
      ? ALL_CHAT_AVAILABLE_BLOCKS
      : ALL_COMPLETION_AVAILABLE_BLOCKS.filter(type => type !== BlockEnum.End)
    return nodes
  },
  getAvailableNextNodes(isChatMode: boolean) {
    const nodes = isChatMode ? ALL_CHAT_AVAILABLE_BLOCKS : ALL_COMPLETION_AVAILABLE_BLOCKS
    return nodes
  },
  checkValid(payload: IterationNodeType, t: any) {
    let errorMessages = ''

    if (!errorMessages && (!payload.iterator_selector || payload.iterator_selector.length === 0))
      errorMessages = t(`${i18nPrefix}.errorMsg.fieldRequired`, { field: t(`${i18nPrefix}.nodes.iteration.input`) })

    if (!errorMessages && (!payload.output_selector || payload.output_selector.length === 0))
      errorMessages = t(`${i18nPrefix}.errorMsg.fieldRequired`, { field: t(`${i18nPrefix}.nodes.iteration.output`) })

    return {
      isValid: !errorMessages,
      errorMessage: errorMessages,
    }
  },
}

export default nodeDefault

Ensure that the description is properly set when configuring the Iteration node in your workflow. This should help in displaying the description as expected [1].
