Bug: edge-runtime-1.73.3 BootFailure — "Unexpected reserved word" on WebSocket proxy function #690

@jpsh-dev

Description

@jpsh-dev

Function: gemini-live-proxy (WebSocket upgrade function using Deno.upgradeWebSocket())
Error: worker boot error: Uncaught SyntaxError: Unexpected reserved word at file:///var/tmp/sb-compile-edge-runtime/gemini-live-proxy/index.ts:1983:28
Runtime: supabase-edge-runtime-1.73.3 (compatible with Deno v2.1.4)

The function was working this morning. No code changes were made. The boot failure started appearing after what appears to be an automatic runtime update to 1.73.3. Reverting to the last known working code still fails. Other edge functions (parse-transaction etc.) continue working — likely because they have cached compiled versions from before the runtime update.
