EC2:enable_snapshot_block_public_access doesn't accept unblocked as argument option

[gabl-ch]

Describe the issue

The doc describes the method as receiving a State argument with three possible values. Though the method actually accepts only two values 'block-all-sharing'|'block-new-sharing'

response = client.enable_snapshot_block_public_access(
    State='block-all-sharing'|'block-new-sharing'|'unblocked',
    DryRun=True|False
)

It should be

response = client.enable_snapshot_block_public_access(
    State='block-all-sharing'|'block-new-sharing',
    DryRun=True|False
)

Since unblocked is not supported, there is a dedicated method to disable the protection.

The error when using unblocked

[cloudshell-user@ip-XXXXXXXX ~]$ aws ec2 enable-snapshot-block-public-access --state unblocked

An error occurred (InvalidRequest) when calling the EnableSnapshotBlockPublicAccess operation: Value 'unblocked' for State is not valid. Valid values are 'block-all-sharing' and 'block-new-sharing'.

Hi @gabl-ch thanks for reaching out. I can confirm the issue you described using the latest versions of Boto3/Botocore. It looks like support for EnableSnapshotBlockPublicAccess was just released in a recent version per the CHANGELOG.

Since the EnableSnapshotBlockPublicAccess API is modeled for use across SDKs, I created an issue for this in our cross-SDK repository: aws/aws-sdk#651. I escalated this issue to the EC2 team so this issue should be addressed soon. Please refer to that new issue I created for updates going forward. Thanks again for reporting this.
