Experiencing the same problem and here is my workaround until the problem is fixed. Manually copy sections in Relume and once you're in Figma, open the plugin and paste the section, which will paste both desktop and mobile versions.
-------------------------------------------
Sent the console log to chatgpt and it replied with this. In case it helps your devs, Dan
From the error you shared, it looks like the Relume Figma plugin is failing to parse the project data it’s receiving from their sync server because the version value in the concepts array is coming back as 7, but the plugin’s Zod schema only allows specific literal values (1, 2, 3, 4, 5, 6).
That’s why you see a chain of Invalid literal value, expected X (value: 7) errors — the schema validation is rejecting the incoming data before the WebSocket connection can fully sync.
What probably happened:
They updated something in their backend so some projects are now using a new version number (7) that the plugin code you have isn’t prepared to handle.
