Cannot call the same chatflow!

Error message

Cannot call the same chatflow!

What it means

Thrown when selectedChatflowId equals options.chatflowid — the chatflow-as-tool would invoke the very chatflow currently running. Same recursion guard as error 346 for the agentflow variant: prevents an infinite HTTP self-call loop.

Solutions

1. Select a different chatflow as the tool target.
2. If self-invocation is truly needed, call the internal logic directly instead of via HTTP.
3. Filter the dropdown so the host flow's own id is not selectable.

Example fix

// before
if (selectedChatflowId === options.chatflowid) throw new Error('Cannot call the same chatflow!')
// after
if (selectedChatflowId === options.chatflowid) {
  throw new Error(`Cannot call the same chatflow (id=${selectedChatflowId}). Pick a different target chatflow.`)
}

function assertNotSelfCallChatflow(targetId: string, hostId: string | undefined) {
  if (targetId === hostId) {
    throw new Error(`Cannot call the same chatflow (id=${targetId}). Pick a different target.`)
  }
}

When it happens

Trigger: A ChatflowTool node pointed at its own chatflow id; dynamic config that resolves to the host id; flow duplicated as a template without retargeting.

Common situations: Building an orchestrator chatflow that mistakenly lists itself; copy-paste of tool config across flows without updating the target.
