Do they not have edge nodes handling TLS closer to the Worker?

No.

I know Prisma has many edge nodes despite having the DB be central.

Oh, interesting. OK then.

Hi! I'm getting a

Connection terminated unexpectedly

Connection terminated unexpectedly

Connection terminated unexpectedly error thrown while trying to query my Postgres DB w/ Hyperdrive. Using almost exactly the example code here:

const client = new Client({
  connectionString: context.env.DB_HYPERDRIVE.connectionString,
});

// Connect to our database
console.log("START CONNECT");
await client.connect();
console.log("END CONNECT");

// Test query
console.log("START QUERY");
const result = await client.query({
    text: "SELECT * FROM pg_tables",
});
console.log("END QUERY");

// Returns result rows as JSON
return context.json({ result: result });

const client = new Client({

console.log("START CONNECT");
await client.connect();

^^ update, I figured out what this was. I'm connecting to an AWS RDS instance. We had our certificate set to

rds-ca-rsa2048-g1

rds-ca-rsa2048-g1

rds-ca-rsa2048-g1

rds-ca-rsa2048-g1, the issue fixed itself when changing back to the default

rds-ca-2019

rds-ca-2019

rds-ca-2019

rds-ca-2019 . Definitely a confusing error message (not sure if this is a

pg

issue, or a Workers issue via the

connect

connect

connect call), but hopefully this can help someone else!

Matt Silverlock•10/16/23, 10:12 AM

This is because Hyperdrive doesn’t yet support custom CAs, and the “newer” AWS CA requires the client (Hyperdrive) to have it in its trust store.

For clarity, after re-reading your message: this is via Hyperdrive, right? Not just

I'm a little bit confused here. The docs do call out custom CA certs, but the default mode in

Correct.

connect()

connect() directly w/

sslmode=REQUIRE

sslmode=REQUIRE

sslmode=REQUIRE

sslmode=REQUIRE doesn't verify the certs, so it works as expected

C

Colin•10/16/23, 2:05 PM

It's only when connecting via Hyperdrive, which I'm assuming is verify-ca or verify-full

M

Matt Silverlock•10/16/23, 2:06 PM

No, per the docs: Hyperdrive does not support those modes. We only support

require

require

require

require (and prefer, but we ultimately require TLS).

C

Colin•10/16/23, 2:06 PM

and the “newer” AWS CA requires the client (Hyperdrive) to have it in its trust store.

I'm a little unsure what you meant by this bit then

C

Colin•10/16/23, 2:06 PM

If we're only using

require

require

require wouldn't cert validation not take place?

CColin If we're only using `require` wouldn't cert validation not take place?

Matt Silverlock•10/16/23, 2:07 PM

Let's step back a second.

You are using Hyperdrive and having issues when using the
```
rds-ca-rsa2048-g1
```
rds-ca-rsa2048-g1
```
rds-ca-rsa2048-g1
```
rds-ca-rsa2048-g1
CA, correct?
When using the raw TCP
```
connect()
```
connect()
```
connect()
```
connect()
API without Hyperdrive you have no issues, correct?

C

Colin•10/16/23, 2:08 PM

correct

CColin correct

M

Matt Silverlock•10/16/23, 2:10 PM

They both share the same egress/TLS path, so this is odd. We shouldn't be validating the cert.

M

Matt Silverlock•10/16/23, 2:10 PM

(We'll look into it)

C

Colin•10/16/23, 2:11 PM

I should add there’s a little bit of fuzziness - I couldn’t immediately see results when changing the database CA, it took <=10m

M

Matt Silverlock•10/16/23, 2:11 PM

AWS says that changing the CA is not an immediate action

C

Colin•10/16/23, 2:12 PM

I interpreted that in the context of it waiting for the next maintenance window (which we forced immediately), not that there’d be propagation delay

C

Colin•10/16/23, 2:12 PM

But that is definitely possible

C

Colin•10/16/23, 2:12 PM

and I’m only assuming the underlying issue is cert validation - the error message was very vague

Colin•10/16/23, 2:20 PM

Sure thing, I added you

K

kian•10/16/23, 4:36 PM

On normal Workers it requires

node_compat

node_compat

which is a set of polyfills (https://github.com/ionic-team/rollup-plugin-node-polyfills/) so I'm not sure if you'd be able to get that working alongside next-on-pages

K

kian•10/16/23, 4:38 PM

Different thing.

K

kian•10/16/23, 4:39 PM

The Pages team don't plan to add

node_compat

node_compat

to Pages, maybe you can ask the next-on-pages team to add it to that framework.

C

Colin•10/16/23, 5:52 PM

node-postgres

node-postgres

node-postgres

node-postgres

other drivers requiring
```
node_compat
```
```
node_compat
```
is a result of the individual drivers, not Hyperdrive, correct?

K

kian•10/16/23, 5:52 PM

Yeah

K

kian•10/16/23, 5:53 PM

Hyperdrive as far as your Worker is concerned is just a connection string

C

Colin•10/16/23, 5:53 PM

I wonder what part of those libs require it + if we'll ever get a "WinterCG-native" PG driver, since I don't think(?)

connect()

connect()

connect()

connect() itself requires it

K

kian•10/16/23, 5:54 PM

I don't think it actually requires them, but they're not conditionally required - esbuild sees they're there, and can't tell that they won't be used at runtime with Workers.

C

Colin•10/16/23, 5:54 PM

I thought that's what separate workerd entrypoint solves

C

Colin•10/16/23, 5:55 PM

^^ or could solve, again I have zero knowledge of these drivers

K

kian•10/16/23, 5:56 PM

node-postgres

node-postgres

node-postgres

node-postgres doesn't have those, so possibly, but I have no idea

C

Colin•10/16/23, 5:59 PM

yeah me neither, and it doesn't impact our Worker luckily, but I've seen a lot of people having the

node_compat

node_compat

vs

nodejs_compat

nodejs_compat

dilemma in this channel so far

How to use hyperdrive in pages functions?

J

James•10/17/23, 12:51 PM

Unfortunately Pages Functions doesn’t support node_compat bundling, nor the hyperdrive binding, so I’m not aware of a simple way to get hyperdrive working with Pages, sorry
