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!

  • Try switching to a different VLI Mode for CIF Number List. For example, use Full Name if you want to map by the object's name.

    Currently, M-Files Importer attempts to match the provided value against both the object ID and name (NameOrInternalID). Since your CIF Number object names are numeric, this can cause conflicts if an object name matches an existing object ID in the vault. For instance, if one object is named 104308 and another object's ID is also 104308, Importer won't know which one to use.

    Also, double-check that there are no duplicate objects. If duplicates exist, Importer may not be able to determine which object to map to.
