Error code

Details

There are 3 main causes for this error:

Your column is corrupted

If the site column is corrupted, try following these steps:

1. Go to the site settings of your SharePoint site in the destination.
2. Click on Site columns in the Galleries section.
3. Look for the name of the site column and click on it.
4. Click Ok.
5. SharePoint should apply the default value to fix the problem.

The column is a lookup that tries to display a field that no longer exists

Often, you get this error when the site column is a lookup that tries to display a field that no longer exists.

Typically, SharePoint defaults to the Title field. In this case, SharePoint cannot find the resource and returns an error.

Because of this, the app cannot display the column name.

You have too many file extension filters in the migration tool 

This can also happen when you have more than 157 file extensions in your migration tool Filter options.

In this case, you have to reduce the number of filters.
