Content type, list definition and List instance - query

Question

Dear all,
I created a list content type, list definition and list instance for a SessionsList.
I did mistake when created a event receiver file where field name is RegistrationsInfo - did typo error as RegistrationInfo. This field I want to make it as false in the ShowInNewForm= false
When I deploy it with event receiver file - I am getting stack trace error stating that the RegistrationsInfo field is missing.
Without event receiver file - when I deploy the solution and checked the field name - it is showing rightly as RegistrationsInfo.

Event Receiver file:-
public override void FeatureActivated(SPFeatureReceiverProperties properties)
//Reference the newly created session list and perform the following
//1. Set the display name of the "Title" column to "SessID" and hide it from the New and Edit Forms
//2. Make the "SessID" column not required
//3. Set the default value of the RegistrationsInfo column to 0 and do not display it on the new form
//4. Add the built-in "Start Date" and "End Date" columns
//Reference the newly created session list
SPWeb currentWeb = properties.Feature.Parent as SPWeb;
//currentWeb.AllowUnsafeUpdates = true;
SPList sessionList = currentWeb.Lists["SessionList"];
//Title column update
SPField titleField = sessionList.Fields["Title"];
titleField.Required = false;
titleField.ShowInNewForm = false;
titleField.ShowInEditForm = false;
titleField.Title = "SessID";
titleField.Update();
//RegistrationsInfo column updates
SPField registrationField = sessionList.Fields["RegistrationsInfo"];
registrationField.DefaultValue = "0";
registrationField.ShowInNewForm = false;
registrationField.Update();
//Add the Start Date and End Date columns to the list, ensure they both display Date and Time, and add them to the default view of the list
SPFieldDateTime startDate = currentWeb.Fields["Starting_Date"] as SPFieldDateTime;
startDate.DisplayFormat = SPDateTimeFieldFormatType.DateTime;
SPFieldDateTime endDate = currentWeb.Fields["Ending_Date"] as SPFieldDateTime;
endDate.DisplayFormat = SPDateTimeFieldFormatType.DateTime;
sessionList.Fields.Add(startDate);
sessionList.Fields.Add(endDate);
SPView defaultView = sessionList.DefaultView;
defaultView.ViewFields.Add(startDate);
defaultView.ViewFields.Add(endDate);
defaultView.Update();
sessionList.Update();
//currentWeb.AllowUnsafeUpdates = false;
Can somebody help me - how to overcome the RegistrationsInfo missing field - error(in the stack trace) when activating the feature in the training site?
Thanks

Hi Sathya,
Seems the field “RegistrationsInfo” is not been found when deploying with Event Receiver, a possible reason is that it might be damaged.
As a workaround, I suggest you retract the solution from your farm, make sure the “RegistrationsInfo” field is deleted using PowerShell, then create another project with the same
content and perform the deployment again.
About how to delete a field using PowerShell for your reference:

Feel free to reply if there any progress.
