I reported the core bug here: AWS SQS node only sends 1 message for two executions triggered in parallel · Issue #20168 · n8n-io/n8n · GitHub
I’m wondering if anyone has a workaround for this?
I have a workflow that triggers a subworkflow for each input item. I can see multiple new executions in the history for the sub-workflow, so I know that part is working. Where it fails is that the SQS node (in the child) only sends one message for both executions. And the execution history shows the same “Message ID” in the SQS node’s output.
Simple workflows that demonstrate and reproduce the bug are included in the GitHub issue link above.
Any ideas?
