I don't know if there is enough information here to formulate a response but I would use data export.
Have you considered using Data Export instead?

@Neal Lu (CN) Thanks for reaching out. The above workflow looks good as you mentioned you only need to use logic app. As per the screenshot the send event was successfully executed. Can you please verify what's the output for the Send event action for any of the successful run. Please share the configuration for the action Send event and how you have verified that the events were not received at the event hub end? Have you configured any application or used service bus explorer to verify it?
