I called aws cognito-idp update-user-pool using the cli with the field TemporaryPasswordValidityDays in the PasswordPolicy and UnusedAccountValidityDays the AdminCreateUserConfig.
The error message was:
An error occurred (InvalidParameterException) when calling the UpdateUserPool operation: Please use TemporaryPasswordValidityDays in PasswordPolicy instead of UnusedAccountValidityDays
I believe the actual error message should have been that UnusedAccountValidityDays cannot be set in AdminCreateUserConfig if TemporaryPasswordValidityDays is set in the PasswordPolicy as written here:
https://docs.aws.amazon.com/cognito-user-identity-pools/latest/APIReference/API_AdminCreateUserConfigType.html
