[BUG REPORT] : GET /dashboards/lookml/{dashboard_id} broken

We’re using this route (through the dashboard_lookml method in the SDK) but starting today we receive a ok: false response, and An error has occured. with a link to a doc that does not exists (https://docs.cloud.google.com/looker/docs/r/err/4.0/500/get/dashboards/lookml/:dashboard_id)

It seems it works for dashboards with numerical IDs but not for “standard” LookML dashboards with string identifiers like some::dashboard. It used to be the case, so wondering if there is any change in the logic for this route?

Can you please investigate this and ensure nothing changed under the hood?

Thank you!
