before:

function replaceInstanceId(elem) {
 +    if (_.isPlainObject(elem)) {
+      return _.mapValues(elem, replaceInstanceId);
 +    } else if (_.isArray(elem)) {
 +      return _.map(elem, replaceInstanceId);
 +    } else if (_.isString(elem) && _.includes(elem, 'instance_id')) {
 +      return _.template(elem)({instance_id: conf.instance_id});
 +    }
 +
 +    return elem;
 +  }

after:

const replaceInstanceId = match({
 [when(Object)]:(elem) => _.mapValues(elem, replaceInstanceId),
 [when(Array)]:(elem) =>  _.map(elem, replaceInstanceId),
 [when.and(String, /instance_id/)]: (elem) =>  _.template(elem)({instance_id: conf.instance_id}),
 [when()]: _.identity
});
