Rest API only works if default flag checked

Hi to all!!
I have an issue with rest api and lucee 5.2.4.37
I tried to configure two rest api, but only one works (one where the default flag is checked, the second where the default flag is not checked as you can see in the screeshots…)

What is wrong with my configuration?
