Unlimited membership lifespan for create user list

[Yingdong Li]

We're getting error  'Too high., at operations[0].create.membership_life_span when trying to create a user list with 10000 as membership lifespan to make it unlimited. Sample code:

val createUserList =
UserListOperation
.newBuilder()
.setCreate {
UserList
.newBuilder()
.setName("name")
.setDescription("description")
.setMembershipStatus(UserListMembershipStatus.OPEN)
.setMembershipLifeSpan(10000L)
.setCrmBasedUserList {
CrmBasedUserListInfo
.newBuilder()
.setUploadKeyType(customerMatchUploadKeyType)
.setAppId(appId.value.getOrElse(""))
.build()
}
}
.build()

val mutateUserListsResponse =
userListServiceClient.mutateUserLists {
MutateUserListsRequest
.newBuilder()
.setCustomerId(customerId)
.addOperations(createUserList)
.setPartialFailure(true)
.build
}
this used to work until recently. We tried with a 500 membership lifespan and it succeeded. We're wondering if there are any changes being introduced to Google Ads API that are related to this? We're on Google Ads API v17.

We saw this error last week too for several days, then it went back to working without our changing anything. We heard from a Google rep "that a change is currently rolling out that removes support for unlimited duration, and the maximum will be 540 days. It's already been changed in serving (unlimited duration is treated as 540 days) but the UI and API are now being updated to match."

Hoping that there is some announcement about what to expect and when this change may be formally made!
