Since libsql/client 5.0: TypeError: not enough arguments at new Database (local replica)

I'm getting this error since upgrading to libsql/client 5.0. The config for createClient is as follows:
{
url: "file:local.db",
syncUrl: config.env.DATABASE_URL,
authToken: config.env.DATABASE_AUTH_TOKEN!,
}

this should work according to the examples provided. The values are not null and work as expected when connecting to the remote db.

$ bun run --watch src/index.ts
63 |       } else if (opts.authToken) {
64 |           authToken = opts.authToken;
65 |       }
66 |       const encryptionKey = opts?.encryptionKey ?? "";
67 |       const syncPeriod = opts?.syncPeriod ?? 0.0;
68 |       this.db = databaseOpenWithRpcSync(path, opts.syncUrl, authToken, encryptionCipher, encryptionKey, syncPeriod);
                     ^

Reproduce the failure from src/db/index.ts using the provided createClient configuration, then inspect the call from @libsql/client/lib-esm/sqlite3.js into node_modules/libsql/index.js. Determine why the local replica reaches databaseOpenWithRpcSync with insufficient arguments and verify that the documented configuration creates the client successfully.
