Postman Embedded Environment Variables Not Being Evaluated - environment-variables

Question

I am using Postman v6.1.4. I am using environment variables heavily. But it appears that pm.environment.get() is not evaluating embedded variables.
I have the following env vars defined in the environment:
addFavDest1:{"ownerId":"{{addFavDest1_ownerId}}","url":"{{addFavDest1_url}}",...}
...
addFavDestArray1:[{{addFavDest1}},{{addFavDest2}},{{addFavDest3}}]
The request body of my API contains:
{{addFavDestArray1}}
The request is sent successfully, with the data I expect, evaluating all of the embedded variables in my environment.
However, when I try to access that env var in my test script, the embedded variables are not being evaluated. For instance, the following:
var addFavDestArray1 = pm.environment.get('addFavDestArray1')
Returns [{{addFavDest1}},{{addFavDest2}},{{addFavDest3}}], with the variables not evaluated.
Is there some way to have the embedded variables evaluated in the environment?

Answer 1

So, in order to handle this situation, I created the following common function that I call from all my tests instead of pm.environment.get('var1') or environment['var1] or environment.var1.
/* funcGetAndEvalEnvVar */
var funcGetAndEvalEnvVar = (varName) => {
const EMBEDDED_VAR_REGEX = new RegExp(`{{\\w+}}`, 'g');
var varValue = environment[varName];
var evalVarValue = varValue;
var reMatch;
while (reMatch = EMBEDDED_VAR_REGEX.exec(varValue)) {
var embeddedVar = reMatch[0];
var embeddedVarName = embeddedVar.slice(2, -2);
if (environment.hasOwnProperty(embeddedVarName)) {
var embeddedVarValue = funcGetAndEvalEnvVar(embeddedVarName);
evalVarValue = evalVarValue.replace(new RegExp(embeddedVar, 'g'), embeddedVarValue);
}
}
return evalVarValue;
};
