Using hyphens in rules

[3goats]

Hi I'm trying perform some additional validation on a JWT. I have a claim within my JWT that looks like this:

"main-application.configuration": "Demo Config"

If I then use this rule to validate it:

config := payload[1].main-application.configuration == "Demo Config" 

I'm getting an unsafe error:

1 error occurred: policy.rego:23: rego_unsafe_var_error: var application is unsafe

The problem seems to be the - (hyphen).

Is there a solution for this ?

Just as how you can use a number ( e.g. 1) in your reference, you can also use strings to deal with situations where the key contains reserved characters:

config := payload[1]["main-application"].configuration == "Demo Config"

or even

config := payload[1]["main-application.configuration"] == "Demo Config"

if main-application.configuration is your key.

Perfect that did the trick. Thanks for the prompt response.
