**What does this issue mean?**

This issue means that you have not linked an 'Internal field' to the 'Channel field name' in the **Mapping** step.

To solve this issue, you need to link an 'Internal field' to the channel field name in the **Mapping** step. For example, for the 'Channel field name' 'availability' you can link the 'Internal field' 'availability'.
