So if anyone else comes across this issue, I finally resolved it by putting a tool node before I did the search for the ID. I told it to sleep for 30 seconds. (Yes, that’s probably longer than necessary, but timing isn’t really an issue for us, because we require approvals.) Apparently, I was doing it correctly, but it was searching before the write was complete and the data was accessible.
Below is the search, which I just placed on an HTTP node.
companies(first: 10, query: “sortKey:CREATED_AT,reverse: true,externalId:externalId:{{8.Id}}”) { nodes {
id
name
externalId
}
}
}
