When attempting to copy an item, ShareGate Desktop displays the following error:
This value is required.
|Any error code ending with: -106|
The error should appear on a given property, for example, Property Status: This value is required.
The error occurs because the destination column is set to require a value and no value is specified for this column, most commonly because the source item does not contain a value in this column.
There are 2 possible solutions to this issue:
1. Temporarily set the problematic column to not be required while you perform the migration with ShareGate Desktop. You can do so by going in the destination list or library settings in SharePoint, then clicking on the column and setting "Require that this column contains information" to No.
2. Set a default value in ShareGate Desktop to use when the source item does not contain a value. This can be done by creating a Custom Template when using Copy SharePoint Content and setting the column to Set mapped value or default.
