ci: bump Node heap to 4 GB for sdk-generation pyright step#43
Merged
Conversation
The Generate workflow has been OOM-crashing on the v2025-11-15 SDKs: FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory Diagnosis (run 26171584374): - Speakeasy CLI's Compile SDK step invokes `uv run python -m pyright` on each generated SDK. - Pyright is a Node.js application. On the v2025-11-15 embedded SDK, pyright's peak RSS is ~3.77 GB (measured locally). - The Generate runner's default Node max-old-space-size is ~2 GB, so pyright OOMs before completing. Reproduced locally: NODE_OPTIONS=--max-old-space-size=2048 → identical OOM NODE_OPTIONS=--max-old-space-size=4096 → pyright passes (0 errors) Pass NODE_OPTIONS via `cli_environment_variables` (the `Gusto/sdk-generation-action` reusable workflow propagates these into the Speakeasy CLI's process env, which pyright inherits via uv → python → node).

Summary
The Generate workflow has been OOM-crashing on the v2025-11-15 SDKs (see run #26171584374):
```
FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory
```
Plumbs `NODE_OPTIONS=--max-old-space-size=4096` through to the Speakeasy CLI's process env via the reusable workflow's `cli_environment_variables` input.
Diagnosis
Local repro
Locally pyright on `gusto_embedded_v_2025_11_15` uses 3.77 GB. Constraining Node to the runner's default heap reproduces the exact CI error:
```
$ NODE_OPTIONS=--max-old-space-size=2048 uv run python -m pyright src/gusto_embedded_v_2025_11_15
FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory
```
Bumping to 4 GB clears it:
```
$ NODE_OPTIONS=--max-old-space-size=4096 uv run python -m pyright src/gusto_embedded_v_2025_11_15
0 errors, 0 warnings, 0 informations
```
