wsProxy config doesnt work anymore in 0.10.4

[marcodejongh]

Steps to reproduce

Setup nextjs up using the websocket proxy & docker approach outlined on: https://vercel.com/docs/storage/vercel-postgres/local-development
Using @neondatabase/[email protected]

Expected result

wsProxy callback is executed, which allows next.js app to connect

Actual result

wsProxy is never executed and all queries fail.

I put a debugger in the wsProxy callback but it was never reached in 0.10.4

Downgraded back to 0.9.5 fixes the problem, havent tried previous versions yet

Environment

Thanks. I'll take a look.

hey, @marcodejongh do you think this error Error: All attempts to open a WebSocket to connect to the database failed. Please refer to https://github.com/neondatabase/serverless/blob/main/CONFIG.md#websocketconstructor-typeof-websocket--undefined. Details: fetch failed

is somehow related to what you are experiencing I am using "^0.9.5" version of @neondatabase/serverless

Sorry for the delay. I don't seem to be able to reproduce the problem. Try this:

git clone https://github.com/jawj/wsproxy-issue-133.git
cd wsproxy-issue-133
npm install
docker compose up -d
node index.mjs

For me, this produces the expected result:

Result {
  command: 'SELECT',
  rowCount: 1,
  oid: null,
  rows: [ { now: 2025-01-15T12:10:22.325Z } ],
  ...
}
