You may need to call a function to parse your string into a geometry? I am not
sure how the CQL parser handles things - perhaps it only expects geometry
literals for spatial filters??
Try using FilterFactory and check if the function works for you?

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
