Please share your workflow

(Select the nodes on your canvas and use the keyboard shortcuts CMD+C/CTRL+C and CMD+V/CTRL+V to copy and paste the workflow.)

Share the output returned by the last node

Information on your n8n setup

  • n8n version:

Hi @Seif :wave: Welcome to the community :cake:

It would be really helpful if you could provide your workflow, and if you could fill out the template fully so we know more about your n8n setup. You can hit cmd/ctrl + a and then cmd/ctrl + c to select and copy all nodes in your workflow, and you can then paste the JSON here in the forums between two sets of three backticks (```) to share your workflow. If your workflow requires outside credentials, any kind of test data you provide would be helpful, but seeing your workflow in general should assist with the expression you’re trying to create.

Can you please also answer the following:

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:
