Redis cached data for the same key is never returned, only continuously added on subsequent requests #246
Description
I have the following:
const client = redis.createClient({ url: 'redis url...' });
const cacheWithRedis = apicache.options({
debug: true,
redisClient: client,
}).middleware;
app.get('*',
cacheWithRedis('1 day', () => true),
(req, res) => {
console.log('post cache, rendering html');
res.render(someHtmlFile);
}
When I run consecutive requests against the server for the same url I always get duplicates of the add to cache logs, but the cached result is never returned.

I have the cache middleware second function return true all the time, but it always goes to the next middleware which actually renders the html on the server and sends it back. Am I missing anything?
