Occasionally getting "Metabase is still initializing" error from metabase API

We are using metabase API(Metabase API documentation | Metabase Documentation) and Occasionally getting "Metabase is still initializing" error.
We set up daily scheduler to call Get Users (Metabase API documentation | Metabase Documentation) around 9-10PM UTC.
We have observed "Metabase is still initializing" happened 2025-06-30T20:35:21, 2025-07-05T20:31:19 and 2025-07-11T21:43:59.

What would be the cause? Is there any workaround to avoid the error?
