## TL;DR

The aserto-node library bundles express helpers, forcing express and its dependency tree on users who use fastify instead. The team shipped exactly that as a new package: topaz-node, available at aserto-dev/topaz-node and on npm, which contains the directory client without the express helpers.

## Steps

1. The aserto-node library bundles express helpers, forcing express and its dependency tree on users who use fastify instead. The ask was for a version with just the gRPC clients.

2. The team shipped exactly that as a new package: topaz-node, available at aserto-dev/topaz-node and on npm, which contains the directory client without the express helpers. The reporter confirmed it exists and works.

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
