Hello
@dnn_s
The errors you're experiencing may be due to multiple clicks on the "Save and Send Test Request" button, which could have led to Multiple triggers(data duplication). For more details, please refer to the attached image.
We recommend setting up the workflow again (you can clone the existing one) and re-establishing the connection with the trigger step. Be sure to click the "Save and Send Test Request" button once. If you want to capture another response use the "Recapture Webhook Response" button. Please test this setup to see if it resolves the issue.
