Amazon Cognito - update email programmatically-CodePudding

I'm trying to update the value of the standard attribute email of a user in a AWS Cognito user pool, but I'm getting this error:

Amazon.CognitoIdentityProvider.Model.InvalidParameterException: user.email: Attribute cannot be updated

The code I'm using is:


AdminUpdateUserAttributesRequest adminUpdateUserAttributesRequest = new()
{
UserPoolId = CognitoUserPoolId,
Username = userDetailMessage.CognitoUsername
};

var emailAttribute = new AttributeType
{
Name = "email",
Value = userDetailMessage.Email
};
adminUpdateUserAttributesRequest.UserAttributes.Add(emailAttribute);

var _ = _client.AdminUpdateUserAttributesAsync(adminUpdateUserAttributesRequest).Result;

The same code is working as expected uptading, for example, a custom attribute, but I cannot use it for updating email attribute.

CodePudding user response：

When you created UserPool you defined schema https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cognito-userpool-schemaattribute.html

For example:

Schema:
        - Name: 'email'
          AttributeDataType: 'String'
          DeveloperOnlyAttribute: False
          Mutable: True
          Required: True

Mutable attribute is answer to your question
