Overview

I attempted to register a CSV like the following using Drupal’s Feeds module.

id	title	target
xxx	aaa	9600023

When you want to register multiple values in a single field like this, the Feeds Tamper module can be used.

The following article was helpful.

By configuring as follows, I was able to batch register multiple values.

However, when the target column contains empty rows like the following,

id	title	target
xxx	aaa

the following error occurred.

Solution

I selected “Skip tampers” as shown below.

Furthermore, I moved “Skip tampers” before “Explode”.

As a result, even when empty strings were included, the error was avoided.

I hope this serves as a helpful reference for those experiencing the same issue.
