Hi @Asaf_Shay, could provide some more context here? I assume you exported the workflow using the command from your previous question and after your changes imported the workflow using a command like n8n import:workflow --input=file.json?
From giving this a very quick go with my local instance, I could export, change and import workflows just fine by running n8n export:workflow --id=1 --output=file.json, then change the name field of the first object in the array inside file.json and then importing everything using n8n import:workflow --input=file.json.
Would you be able to describe the steps you took in more detail and also share the file you have exported and imported?
