From prisma 6.2+ it's not working at all.

For anyone running into issues with >= Prisma 6.2, you can get around it by initializing PrismaClients with the constructor and passing them into the extension as replicas, rather than urls.

    return client
        .$extends(
            readReplicas({
                replicas: (readonlyUrls ?? []).map((url) => new PrismaClient({ datasourceUrl: url })),
            })
        );

Hey everyone!

We released a new version of read-replicas extension - 0.4.1.

https://www.npmjs.com/package/@prisma/extension-read-replicas

Can you please upgrade to the latest version and confirm if the issue is resolved?

[meotimdihia]

@nurul3101 I confirm the problem was solved. I have been using it on high-traffic production for 2 days already.

We've also been operating it in production for a while – seems fine.
