Wrangler 4.50.0 breaking (?) Hyperdrive connections

[marble prawn]

I suspect that this:
https://github.com/cloudflare/workers-sdk/pull/11219
Potentially caused an issue with Hyperdrive connections not working and they crash in this version of Wrangler and newer.
Error:
Error: read ECONNRESET
at TCP.onStreamRead (node:internal/stream_base_commons:216:20) {
errno: -4077,
code: 'ECONNRESET',
syscall: 'read'
}

As soon as I remove Hyperdrive and use the raw connection string for the database, it does not crash.

I am on Windows 11 x64

@marble prawn can you paste aredacted wrangler file so I can attempt to recreate this? Are you using localConnectionString?

[marble prawn]

Thank you for your message. Here is a redacted wrangler config:

"compatibility_flags": [
"nodejs_compat",
"nodejs_compat_populate_process_env",
],
"placement": {
"mode": "smart",
},
// Hyperdrive
"hyperdrive": [
{
"binding": "HYPERDRIVE",
"id": "hyperdrive id",
"localConnectionString": "postgres connection string here",
},
],

And we are using env.HYPERDRIVE.connectionString to connect to the database with Prisma. Note that this issue only started happening from Wrangler 4.50.0 and onwards. I have tested various versions of wrangler to determine that this is the version where the issue started.

Thanks again and please let me know if you need more info.

Thanks, and this is on Windows only? Are you using WSL or Windows for development?

[past iron]

I've replicated this and will open a bug

I only use Windows for this project. If you'd like, I can try WSL.

[marble prawn]

Thank you! we are looking forward to a fix. for now, we are using an environment variable when in development instead of the hyperdrive connection string.

Hi, I’m experiencing a similar issue as well. May I ask if you are trying to establish the connection using SSL? If so, which sslmode are you currently using?

[marble prawn]

it doesnt seem to matter what mode is used for me

[quiet bloom]

Hmm, that's interesting thanks for testing. I was experiencing same issue and changing ssl-mode helped for me. Just curious if it would help.

hmm i see
