The message appears when you save property values on a variation. It shows that a value of the property has no language or an invalid language code. Text and HTML properties must always be linked to a valid language.

How to recognize the problem

You change the value of a property and save. The message Invalid language for values of this property. appears, often for several variations or items. You cannot see the faulty entries in the interface.

Cause

A value is linked to the property without a language or with a language code that does not exist in PlentyONE. One example is the country codes CH and AT, which are not valid language codes. Valid language codes are, for example, de, en, fr and nl. Such entries are usually created via an import or the REST API and not via the interface.

How to fix the error

1. Open the affected variation under Items & Stock » All items.
2. Note down or export the values of the affected property so that you can enter them again later.
3. Remove the link between the property and the variation. The faulty entry is removed as well.
4. Link the property again and enter the value with a valid language.
5. If many variations are affected or you cannot find the faulty entry, contact support. Support can remove invalid entries.

Use only valid language codes for imports.
