Create Sensor RestAPI

Hello, I'm creating a sensor using Rest Custom to capture the information through JsonPath expression. I noticed that when I create a template to filter the result of a line that contains separator "-" PRTG cannot bring the result, it seems that the character "-" breaks the index. Is there a parameter to prevent PRTG from understanding the "-" as a separator? I already tried: " ", ' ', { }, [ ] but none worked. Here are the details of the sensor I'm trying to create: Input:

Note: When I use the same expression on https://jsonpath.com/ the result is shown normally.

Example of when the line observed does not have the "-" in the same Input: Template in PRTG:
