Hi,

You cannot use the “/” in your user name.

Some naming guidelines are here

Acceptable characters are lowercase letters, uppercase letters, numbers, ‘\_’, ‘-’ or ‘.’.

Create user name according the above pattern.

@Naveed I am not adding “/” character. Quicksight its self creating the username with this format. its not allowing me to set the user name even its mentioned in [register\_user - Boto3 1.34.68 documentation](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/quicksight/client/register_user.html). So, i have not added UserName parameter in Request, but QS itself created that with this character and format.

Hi,

I think if any character in user name is not as per format as I mentioned It will create an issue.

@Ganesh_Pasarkar ,

I believe your users are federating into Quick Sight. The uniqueness for a user in Quick Sight when federating using a specific role is of the format : iamrolename/sessionname

Kind regards,

The format is iamrolename/sessionname . The session name would be the attribute from your identity provider that user is federating from. This could be the email address for eg. You could look into customizing those at your end.
