Column doesnt exist error - Sharepoint Deployment

Question

I am getting an error while deploying a project to the Timer Jobs. It keeps shooting me an error that says "Column does not exist", when I go to my list and my code, there is no such variable or column as what they are describing. Is there anything that I should troubleshoot to find a solution?

Here is a bit of my stack Trace:

Answer 1

It looks like you have a namespace called New_PhoneBook with a class within it called TimeJob. The error is coming from the Execute method.

The code you're looking for within that method is the part that changes the value of a list item and updates it. For example:

item["PhoneBook"] = "value";
// or
item[internalName] = "value";

// and

item.Update();
// or
item.SystemUpdate();

If the name of the field is unfamiliar, then this call may well be in a for loop on a list's fields, and the item may be the result of an earlier query that does not include that field.

Answer 2

Is "PhoneBook" an alias for a another column like "Title"? Did you mean "Phone Book" instead of "PhoneBook"? Somewhere in your code you are referencing a column called "PhoneBook" - that is why you are getting an error on .GetField( fieldname,..)

Answer 3

This happens when you change/update your column name what sharepoint does it update the column display name only and the internal name remain same.

To get the correct col name always do the below:

1. Go to List Settings Page and Click on the Column you want to use in code

2. Copy the column name from the URL
