Wenquan,  
Has the max retention period been changed? We used to put 90 days but for a new namespace, perhaps after an upgrade, it’s not letting me.  
Also, can you please improve this error message? “A valid retention period is not set on request.” should tell us what the constraints are.  
Thank you.

the max 30 days retention is always there

> <https://github.com/temporalio/temporal/blob/v1.0.0/common/constants.go#L107>

> <https://github.com/temporalio/temporal/blob/v1.0.0/service/frontend/workflowHandler.go#L238>

there was however a bug in update namespace API which omits the retention check, which is fixed here: [Add missing retention days check on update namespace API by wxing1292 · Pull Request #1407 · temporalio/temporal · GitHub](https://github.com/temporalio/temporal/pull/1407)
