CI issues related to Nx Cloud: #9584 #9334 #9310

Problem

The CI pipeline has been timing out after 1 hour with the error

NX   No new completed tasks after 3600 seconds.

Maybe Root Cause

In commit eee4405, the workflow was refactored with the following changes

• Removed the agents job that was starting 3 distributed agents
• Added tanstack/config/.github/setup@main for simplified setup
• Added --parallel=3 flag to the test command

However, the environment variables still had

• NX_CLOUD_DISTRIBUTED_EXECUTION: true
• NX_CLOUD_DISTRIBUTED_EXECUTION_AGENT_COUNT: 3

This created a configuration mismatch where

1. The main job starts the CI orchestrator with npx nx-cloud start-ci-run
2. The orchestrator waits for 3 agents to connect (as configured)
3. No agents actually start (since the agents job was removed)
4. After 1 hour of waiting, the job times out

Solution

Set NX_CLOUD_DISTRIBUTED_EXECUTION: false to align with the simplified workflow structure. This ensures tests run directly in the main job.

Note

While we cannot fully replicate the GitHub Actions environment locally, this analysis is based on

• The observed CI behavior and error messages
• Local testing confirming tests pass without distributed execution
• The clear mismatch between the workflow structure and configuration
