[jinhon-chen]

as running "Use the graph", there are something wrong:

TypeError: string indices must be integers, not 'str'
During task with name 'web_search_node' and id '64250822-9000-ddc1-2589-b29219660108'

Can someone tell me why?

It seems that you posted the comment on the wrong page, because there is no tutorial on this page.
Also, your error seems to be a mistake in the tool.
