Hi everyone, I am having an issue where I am trying to import data into a field which is a "List" field, so the field contains the list from an object called CIF number. I have added the barcode number as a field as this is the unique ID.

I keep getting an exception "Assigning value '221870' to the M-Files property definition ID 1057 failed" as below fromt he importer.

So i have added an object called CIF number list (green) and added it as a drop down list to the metadata card, however when importing it wont accept it. However if i add as a "TEXT" field (yellow) it accepted the information. Is there any way to import into a "list" field otherwise i will need to update over 3.5k metadata cards manually?

Thank you!
