I am using a spatial filter to test if a candidate polygon is within the base polygon. The settings for the spatial filter are as follows:
Filter Type - Single Filter
Pass Criteria - Pass against one filter
Support Mode - Support aggregates
Spatial Predicates to test - Contains Candidate
Use bounding box - no
Curve boundary rule - default
For some reason it keeps failing and I'm not sure why. I've attached a sample of the data.

@chris28 Thanks for including some example data. For the Contains to work, if the boundaries touch, then the boundaries would have to match exactly. If there are any overlaps of the boundaries, where the boundaries cross, then Contains will fail. Since there are no vertices on the Base where the Candidate appears to touch then it's unlikely the edges match exactly.
You can illustrate this if you compare the Base to itself - it will pass.

What would the setting need to be then for this to pass? Or is there a different transformer that would work better?

You could set the Spatial Filter to intersects as well as contains. Other transformers to look at are AreaOnAreaOverlayer and Intersector. These both have tolerance attributes that you can set. They will however breakdown geometry so once you've determined the relationships, you'll need to transfer this back to the original geometries.
