CLI: User pool update with cli-input-json fails validation with fine JSON

Question

Hello,  
trying to execute an user pool update with parsable and valid JSON file via CLI using
 `aws cognito-idp update-user-pool --user-pool-id AWSRegion_PoolID  --cli-input-json file://./input.json`
 command, I got as validation error

```
Parameter validation failed:
Unknown parameter in AdminCreateUserConfig: "TemporaryPasswordValidityDays", must be one of: AllowAdminCreateUserOnly, UnusedAccountValidityDays, InviteMessageTemplate
```

but can't figure out what's wrong in input JSON...  
The following is an excerpt

```
  "AdminCreateUserConfig": {
    "InviteMessageTemplate": {
      "EmailMessage": "Il nome utente è {username} e la password temporanea è {####}. ",
      "EmailSubject": "La tua password temporanea",
      "SMSMessage": "Il nome utente è {username} e la password temporanea è {####}. "
    },
    "UnusedAccountValidityDays": 14,
    "AllowAdminCreateUserOnly": false
  }
```

so _TemporaryPasswordValidityDays_ is not specified here.  
I could have miss something, but can't figure out what... can someone help or give any advice? TY

Answer

I tried mixed configurations and in the end I got a successful update by deleting _AdminCreateUserConfig.UnusedAccountValidityDays_

Answer

Since I was using v1 AWS CLI, I thought that using v2 could have a passed validation, so I upgraded.  
  
Now, using the same update command, I got
 `An error occurred (InvalidParameterException) when calling the UpdateUserPool operation: Please use TemporaryPasswordValidityDays in PasswordPolicy instead of UnusedAccountValidityDays`
 with

```
    "PasswordPolicy": {
      "RequireNumbers": true,
      "RequireLowercase": true,
      "RequireSymbols": false,
      "RequireUppercase": true,
      "TemporaryPasswordValidityDays": 14,
      "MinimumLength": 8
    }
```

, so the issue seems again about _TemporaryPasswordValidityDays_ just changed a little.  
  
This thing started puzzling me a lot... by comparing update skeleton or even reading AWS CloudFormation reference for _AWS::Cognito::UserPool PasswordPolicy_  we are allowed to use TemporaryPasswordValidityDays.  
Comparing for what is raised on error, the only occurence for _UnusedAccountValidityDays_ is in another part of the file

```
  "AdminCreateUserConfig": {
    "UnusedAccountValidityDays": 14,
    "AllowAdminCreateUserOnly": false,
    "InviteMessageTemplate": {
      "EmailSubject": "AIR - La tua password temporanea",
      "SMSMessage": "Il nome utente è {username} e la password temporanea è {####}. ",
      "EmailMessage": "Il nome utente è {username} e la password temporanea è {####}."
    }
  },
```

that I can see still valid at  as AWS CloudFormation reference.  
  
So now I start doubting about validation...  
  
The side questions are now: What is the purpose of validation that raises error when input is fine? Is it possible to skip this kind of validation?  
Thanks
