Groupify already created sharepoint site

[Dipali-arup]

Using TeamSiteCollectionGroupifyInformation to Groupify existing site collection which has been created using TeamNoGroupSiteCollectionCreationInformation .

var groupifyprjsite = new TeamSiteCollectionGroupifyInformation
{
Alias = aliasName,
DisplayName = siterequestmessage.TeamOrSiteName,
IsPublic = false,
KeepOldHomePage = true,
Description = siterequestmessage.SiteDescription,
Owners = receivedSiteOwners,
SiteAlias = aliasName
};
tenant.GroupifySite(siterequestmessage.SiteUrl, groupifyprjsite);

Calling GroupifySite method throws exception as below:
{"An error occurred while processing this request."}
"System.Data.Services.Client.DataServiceRequestException"

Has anyone encountered this issue before? Any pointers to proceed ahead would be appreciated.
Thank you,
