Avoid using `eval()` in `usage` package

## Is your feature request related to a problem? Please describe.
Warnings during the build step of the usage package

## Describe the solution you'd like
Can use `.split(".")` to get the first two words `(model, operation)`, and the rest will be query. Using `JSON.parse()` on the rest of the string will circumvent using `eval()` and therefore get rid of the warnings during build.
