  It is because, when you don't have "targetsAndToolsNeedGrouping" : true, it only uses the tools, not the targets. It is link the normal Boolean feature

  To elaborate a bit on what @mbartlett21 said:
  The preferred way to do a simple boolean union is to put all the bodies to merge into the "tools" field. You can do this by combining multiple queries with qUnion.
  

  <div>opBoolean(context, id + "boolean1", {
          "tools" : qUnion([
                  firstEntities,
                  secondEntities
              ]),
          "operationType" : BooleanOperationType.UNION
  });<br></div>

  "targetsAndToolsNeedGrouping" provides a more complex behavior, which can be useful for when a single union is grouping multiple sets of disjoint bodies. For a simple union of two parts, the above code is sufficient (and will more accurately report when the union did not have any effect).

  Oh Okay.  Thanks for pointing this out Kevin.   My one tiny criticism of the Featurescript project is its apparent lack of a 'cookbook' type of guide.   The idea of the cookbook is to compile a whole bunch of little examples of the sort where you say 'now suppose you want to do this, then here is a little example code snippet that does it.'   I think that's the   way most people learn something.

  Thank you, this helped.

  THANK YOU, THANK YOU, THANK YOU. After days of fighting issues, recruiting AI's (claude, GPT5) and literal countless attempts, your solution to add that one line resolved all my issues. God bless you for posting your finding.
