Exclude Null From Rollup

[BuildLikePeter (Peter)]

I am using the rollup formula to create an array. It is returning null for one of the array values. How can I return the rolled up array without the nulls?

You could use the filter formula to check that the value isn’t null, which will give you a cleaned array

Add .filter(x => x != null)
