Parameter resolution in sub-nodes

Sub-nodes behave differently to other nodes when processing multiple items using an expression.

Most nodes, including root nodes, take any number of items as input, process these items, and output the results. You can use expressions to refer to input items, and the node resolves the expression for each item in turn. For example, given an input of five name values, the expression {{ $json.name }} resolves to each name in turn.

In sub-nodes, the expression always resolves to the first item. For example, given an input of five name values, the expression {{ $json.name }} always resolves to the first name.

节点选项(Node options)#

  • 模型：选择用于生成嵌入的模型。
  • 基础 URL：输入要发送请求的 URL。如果你使用的是自托管的类似 OpenAI 的模型，请使用此项。
  • 批量大小：输入每次请求要发送的最大文档数量。
  • 去除换行符：选择是否从输入文本中删除换行符（开启）或不删除（关闭）。n8n 默认启用此功能。
  • 超时：输入请求可以花费的最大时间（以秒为单位）。设置为 -1 表示没有超时。
