❌ What's Broken
Issue #1: AgentDB Module Not Found
Severity: 🔴 CRITICAL - BLOCKING
Error:
Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/app/node_modules/agentdb/dist/index.js'
imported from /app/src/federation/FederationHubServer.ts
Root Cause:
The agentdb package is referenced in federation code but:
- Not published to npm
- Not included in Docker build context
- Local symlink (if exists) not preserved in Docker
Affected Files:
src/federation/FederationHubServer.ts- line 12src/federation/FederationHub.ts- line 12src/federation/FederationHubClient.ts- line 7src/federation/EphemeralAgent.ts- line 79
Impact:
- ❌ Hub container exits immediately (exit code 1)
- ❌ All agents fail dependency check
- ❌ System cannot start
🔧 Fixes Required
Fix #1: Resolve AgentDB Dependency
Option A: Bundle AgentDB in Docker (Recommended)
# Dockerfile.hub.new
FROM node:20-slim
WORKDIR /app
# Copy package files
COPY package*.json ./
# Copy agentdb source
COPY src/agentdb ./src/agentdb
# Install dependencies
RUN npm install
# Copy rest of source
COPY src ./src
COPY wasm ./wasm
# Create data directory
RUN mkdir -p /data
EXPOSE 8443 8444
CMD ["npx", "tsx", "docker/federation-test/run-hub.ts"]
Option B: Make AgentDB Optional
Modify federation code to work without AgentDB:
// src/federation/FederationHubServer.ts
let AgentDB;
try {
AgentDB = await import('agentdb');
} catch (e) {
console.warn('AgentDB not available, using SQLite only');
AgentDB = null;
}
Option C: Use Pre-built AgentDB
Build agentdb separately and copy into Docker:
# Build agentdb first
cd src/agentdb
npm run build
# Then build Docker images
cd ../../docker/federation-test
docker-compose build
