Data Action HTTP timeout hardcoded to 3s?

Built a custom external data action in Architect that hits our internal API. The endpoint is solid and usually responds in 2s, but under load it hits 5s. Architect kills the request with a generic timeout error every time. Tried increasing the timeout in the Data Action config, but it seems capped at 3 seconds. Is there a way to override this limit via API or is it a hard platform constraint?

“timeout”: 5000

It's not hardcoded, just misconfigured. The Architect UI caps it, but the API accepts higher values. I hit this with my C# integrations too. Use `PATCH /api/v2/architect/dataactions/{id}` and set `timeout` in milliseconds. Works fine from there.
