FYI, I also got the “Internal server error” when trying to build a dashboard. This error is due to v0 credits, as it appears in a debug Teable log displayed before the error log :
"message":"HTTP 402: {\"error\":{\"type\":\"payment_required_error\",\"message\":\"You are out of credits. Add more or enable Auto-topup at https://v0.app/chat/settings/billing\"}}"
