CI: Generate VRChat API SDK failing with ERR_REQUIRE_ESM from openapi-generator-cli

[MineTech13]

Summary
The "Generate VRChat API SDK" workflow is failing at the "Set OpenAPI Generator version" step (job 89768817411). The OpenAPI Generator CLI main.js attempts to require() proxy-agent, but an ESM-only proxy-agent is installed which causes Node to throw ERR_REQUIRE_ESM and the job to exit with code 1.

Relevant logs
Error [ERR_REQUIRE_ESM]: require() of ES Module /home/runner/.../node_modules/proxy-agent/dist/index.js from /home/runner/.../node_modules/@openapitools/openapi-generator-cli/main.js not supported.
Instead change the require of index.js in .../node_modules/@openapitools/openapi-generator-cli/main.js to a dynamic import() which is available in all CommonJS modules.

Workflow & run

• Workflow file: .github/workflows/ci.yaml
• Failing run: https://github.com/vrchatapi/vrchatapi-java/actions/runs/30192746745/job/89768817411

Steps to reproduce

1. Trigger the "Generate VRChat API SDK" workflow (or run locally with the same steps).
2. Observe failure when running: ./node_modules/@openapitools/openapi-generator-cli/main.js version-manager set 6.2.1

Impact
Blocks automatic SDK generation and the release/tagging steps in CI.

Suggested quick fix
Force-install a CommonJS-compatible proxy-agent (v5.x) so @openapitools/openapi-generator-cli resolves a CJS proxy-agent instead of an ESM-only build. Update the workflow to create a temporary package.json with an npm "overrides" entry before installing the CLI. Example:

• name: Prepare npm override and install OpenAPI Generator CLI
  run: |
  cat > package.json <<'JSON'
  {
  "private": true,
  "overrides": {
  "proxy-agent": "5.0.0"
  }
  }
  JSON
  npm install @openapitools/openapi-generator-cli

• name: Set OpenAPI Generator version
  run: npx @openapitools/openapi-generator-cli version-manager set 6.2.1

Alternate fixes

• Commit a package.json to the repo that pins proxy-agent to v5 (persistent fix).
• Install proxy-agent@5 before the CLI install: npm install proxy-agent@5 --no-save; npm install @openapitools/openapi-generator-cli
• Use an @openapitools/openapi-generator-cli version that depends on a CJS proxy-agent.

Notes

• The problem is an ESM/CJS incompatibility (ERR_REQUIRE_ESM) caused by proxy-agent being distributed as an ES module while the CLI expects CommonJS.
• This was observed on the GitHub Actions runner in the logs for job 89768817411.
