TypeError: Cannot read properties of undefined (reading 'replace')

[andreujuanc]

Same as with this issue: https://github.com/kysely-org/kysely-postgres-js/issues/9

I'm using latest of everything and this is on nextjs 14, node 20.

I tried to understand the problem but I failed to do so. I rolled back to pg and worked fine, therefore I think it's either postgres or this adapter.

Hey 👋

Can you paste your package.json's dependencies object or provide a reproduction repository?

[andreujuanc]

Hi @igalklebanov , sorry but I already migrated out of nextjs. I think MAYBE the problem is that the connection string was undefined. Not completely sure, but that might be. Sorry.

Hey, @igalklebanov

I have the same error as op

Exactly same issue, while default pg dialect works as should.

[igalklebanov]

"kysely-postgres-js": "^2.0.0", "pg": "^8.11.3"

Hey 👋

This has pg in it, instead of postgres as postgres client library. Try npm i postgres@3.4.1.

[lpite]

same problem next 12.3.4 or next 14

I got the same problem as well, here's the error it gives

This project is purely express running on Node 20 on docker container in a kubernetes cluster.

[igalklebanov]

This seems related to postgres, and not this package as all stack traces thus far lead to https://github.com/porsager/postgres/blob/master/src/connection.js#L389

Try using your postgres instance outside of Kysely with the same options - does it still throw an exception?

[igalklebanov]

Closing this.

Tests are passing with Node LTS, postgres@latest, kysely@latest. https://github.com/kysely-org/kysely-postgres-js/actions/runs/8107957535

Was able to reproduce the same exception when docker container was down or by passing a wrong host option. Seems to happen because a connection cannot be established - could be due to many reasons.. the connection options are missing/wrong at runtime, your database instance refuses connections from your network OR your database instance requires something additional, SSL perhaps?

Not related to Kysely or kysely-postgres-js.

I guess it unrelated to this adapter but host is valid because it works for some time and than nextjs hot reload crashes it and after server restart it works again

I can confirm that this is related to a malformed URL. In my case I had a ?schema= in my connection string and postgres-js didn't like it. cc @porsager, it's a cryptic error message and might be worth exploring a fix.

Yeah maybe but i use credentials not url and error still happens

I remove ?schema= from url and it work
