n8n API Connection 404 Error: Need Help with Region Settings

Hey guys! While testing the API connection with n8n I get a 400 error even though the API key and the workspace key are correct. We noticed that the problem is that the connection only works when the region in the n8n Dust node is set to US even though Dust API should also be served from https://eu.dust.tt (europe-west1). Could you explain and help us find a solution, please? Thanks!
