The numbers in the logs for
FeedItemService.get() are the ids of the attributes in the feed. It is not same as the "ID" in
this table. To map the respective attribute in a Feed to the "ID" in the table corresponding to a placeholder type, you can do a
FeedMappingService.get() and filter with
FeedId. You will see how each
feedAttributeId in the feed is mapped to the respective
fieldId in the table corresponding to the placeholder type. If an attribute in a feed is having a blank value, it might not return the value for that attribute in the API response. In this case, the attribute 10 in one of feeds was corresponding to "Item 2 header" and the attribute 10 in the second feed was corresponding to "Item 1 final mobile URL" which was also blank.
