Unable to Update contact on Form Submit

Question

I am working on Sitecore 9.0.2 and created a custom Update contact logic where I am storing Firstname, email and Custom facet to xDB. This fails if the person filling the form is an existing user.

Log says:

I was getting this issue with two facets: PhoneNumbers and Customfacet when i added Phonenumber to ExpandOptions the error was resolved for phone numbers but it still persists for RYIForm. Code snippet below:

var expandOptions = new ContactExpandOptions(CollectionModel.FacetKeys.PersonalInformation, CollectionModel.FacetKeys.EmailAddressList, RYIFacets.DefaultFacetKey, "PhoneNumbers");

Thanks, Samridhi

You need to check first if the facet already exists, the code to get or create the RYIFacets facet could like this:

var contact = context.Contact;
var facet = contact.GetFacet<RYIFacets>(RYIFacets.DefaultFacetKey);

if (facet == null)
{
facet = new RYIFacets();
}

When working with a facet, not all data is always loaded, so check.
