Taking a look at this running under 21: https://trycf.com/gist/7780764e700b879cca4dc86aa5fa7431/acf2021?theme=monokai And in ACF2016 https://trycf.com/gist/275b0f6c7e000edcb4e5ef63e8f09d7a/acf2016?theme=monokai The difference is that

"1"

is converted to a boolean in 2016 and maintained as a string in 2021. This is actually good and an improvement. However, it means many changes in the app that I am upgrading and I am wondering if there is an EASY, lazy man's way out to make the serialization behave like 2016's? This is not using any framework, it's using a simple

serializeJSON()

to serve CF structures. I am aware that I could probably create an aspect for the JSON responses, or use CFC serialization metadata, or change the code, but like I said is there an easy way out to try and implement and run the Unit tests against it, until someone goes through the code properly?
