I am developing GroupUserAdding event receiver in which I am using SPEventReceiverStatus.CancelNoError but it is still throwing error Sorry, something went wrong when someone tries to add user in group. It is for SharePoint 2016.

Why is this throwing error when it should not?

Here is my code:

public override void GroupUserAdding(SPSecurityEventProperties properties)
{
    base.GroupUserAdding(properties);
    base.EventFiringEnabled = false;
    properties.Status = SPEventReceiverStatus.CancelNoError;
    base.EventFiringEnabled = true;
}

    Hi @Frank Martin ,

    The SPEventReceiverStatus.CancelNoError status is used to cancel the event without showing an error message. However, if there is an underlying issue, such as permissions or configuration problems, it might still result in an error. Check the SharePoint ULS logs for more detailed error messages that could provide additional insights.

    Permissions: Ensure that the account running the event receiver has the necessary permissions to add users to the group. Lack of permissions can cause unexpected errors.

    Code Adjustment: Try adjusting your code slightly to ensure the event firing is handled correctly. Here is a revised version of your code:

    public override void GroupUserAdding(SPSecurityEventProperties properties)
{
    base.EventFiringEnabled = false;
    properties.Status = SPEventReceiverStatus.CancelNoError;
    base.GroupUserAdding(properties);
    base.EventFiringEnabled = true;
}
