Description
The fields are populated with the field names from the selected layer or table. But if a file path is used, since the layer or table is not loaded, the fields are not populated, and cannot be selected.
Solutions:
1) allow typing the field names in this case, not selecting from combobox
2) reading the selected file if possible and populate the combo boxes
3) do not allow files to be selected in this situation, only loaded layers or tables
up to qgis 2.18, 3) was the way this was implemented
Setting this as high priority, since it was ok in QGIS 2.x

Can you elaborate? It works ok for me. If a file path is selected the layer is transparently loaded in the background and used to populate the fields list.
