Examples 57/63/63c fail to run: 'Top-level await not supported with cjs output' (TransformError under npx tsx)

[deeptireddy-lab]

Summary

Three agent examples cannot be run with the documented command (npx tsx examples/agents/<file>.ts) — they fail at transpile with TransformError: Top-level await is currently not supported with the "cjs" output format. They use top-level await, but the package resolves to CommonJS output under tsx, and CJS can't have top-level await.

Environment

• conductor-oss/javascript-sdk @ main, tsx (bundled), Node 24, macOS
• (env/server irrelevant — failure is at transpile, before any server/LLM call)

Repro

cd javascript-sdk
# a normal example runs fine with the documented command:
export AGENTSPAN_SERVER_URL=http://localhost:8080/api AGENTSPAN_LLM_MODEL=anthropic/claude-sonnet-4-6
npx tsx examples/agents/01-basic-agent.ts        # → COMPLETED

# these 3 never compile:
for f in 57-plan-dry-run 63-deploy 63c-run-by-name; do
  npx tsx examples/agents/$f.ts
done

Actual

examples/agents/57-plan-dry-run.ts:69:23: ERROR: Top-level await is currently not supported with the "cjs" output format
examples/agents/57-plan-dry-run.ts:90:2:  ERROR: Top-level await is currently not supported with the "cjs" output format
examples/agents/63-deploy.ts:75:17: ERROR: Top-level await ...
examples/agents/63-deploy.ts:88:2:  ERROR: Top-level await ...

examples/agents/63c-run-by-name.ts:33:2:  ERROR: Top-level await ...
  name: 'TransformError'

01-basic-agent.ts COMPLETES with the exact same command → the run command is correct; these 3 specifically can't compile.

Cause

The examples use top-level await, but the SDK package is CommonJS (no "type": "module"), so tsx emits CJS output, which does not support top-level await.

Suggested fix

Either wrap the top-level await calls in an async function main() { ... } main() (matching the other examples), or make the examples run as ESM.
