Hello community,
I am trying to check whether a contact reference on salesorder entity has its email address field filled or not.
After checking in the code, I went to salesorder entity tried to activate the record and then I got this exception:
Error in function ValidationUtil.activateSalesEntity.executeAction(): Unexpected exception from plug-in (Execute): Ewe.Xrm.Workflows.SalesEntityValidator.SalesEntityValidator: System.NullReferenceException: Object reference not set to an instance of an object.

My C# Function is as followed:
Share
Report private void ValidateIfAnsprechpartnerEmailAddressIsFilled()
{
var salesOrder = LocalContext.BaseEntity.BaseEntity;
var ansprechpartnerRef = salesOrder?.GetAttributeValue(SalesOrder.Properties.vis1_ansprechpartnerid);
var ansprechpartnerMailAddress = LocalContext.Manager.Retrieve(ansprechpartnerRef, "emailaddress1");
if (string.IsNullOrWhiteSpace(ansprechpartnerMailAddress.GetAttributeValue("emailaddress1")))
{
ValidationsFailures.Add("Für den gewählten Ansprechpartner fehlt eine E-Mail-Adresse.");
}
