Hi @fxholl, I am sorry to hear you’re having trouble. It seems your example workflow requires access to a specific sheet and credentials on the HTTP Request node to run so I wasn’t able to execute this exact workflow.
When trying to replace these nodes/settings the workflow does however execute fine for me on n8n desktop:
Are you by any chance trying to run the SplitInBatches node on its own? I’ve seen this causing trouble in the past, running the whole workflow does usually resolve the problem though.
