Property FeatureValue: value is not valid

Your CSV import process stops and displays the following error:

Fatal error: Uncaught exception 'PrestaShopException' with message 'Property FeatureValue->value is not valid'

This error means that a feature value used by one of the products of your CSV file contains an invalid character, such as ^<>;=#{}

Download the corresponding TODO file to check which product uses this feature value to then fix the problem in Store Commander.

You will then be able to start your import again.
