If you are asking about a problem you are experiencing, please use the following template, as it will help us help you. If you have a different problem, please delete all of this text 🙂

TIP 1: select at least one tag that further categorizes your topic. For example `server` for APM Server related questions, `java` for questions regarding the Elastic APM Java agent, or `ui` for questions about the APM App within Kibana.

TIP 2: Check out the [troubleshooting guide](https://www.elastic.co/guide/en/apm/get-started/current/troubleshooting.html) first. Not only will it help you to resolve common problems faster but it also explains in more detail which information we need before we can properly help you.

**Kibana version** :  
7.4.0  
**Elasticsearch version** :  
7.4.0  
**APM Server version** :  
7.4.0  
**APM Agent language and version** :  
elastic-apm-node: 3.6.1  
**Browser version** :  
Google Chrome  
Version 83.0.4103.116 (Official Build) (64-bit)  
**Original install method (e.g. download page, yum, deb, from source, etc.) and version**:  
Installed elastic-apm-node via npm  
**Fresh install or upgraded from other version?**  
Fresh install  
**Is there anything special in your setup?** For example, are you using the Logstash or Kafka outputs? Are you using a load balancer in front of the APM Servers? Have you changed index pattern, generated custom templates, changed agent configuration etc.  
I have replicated the issue in an opensource project

**Description of the problem including expected versus actual behavior. Please include screenshots (if relevant)**:  
Configured node APM with,

```auto
    require('elastic-apm-node').start({
      serviceName: 'redis-test',
      asyncHooks: true,
      serverUrl: 'http://localhost:8200',
      logLevel: 'trace'
    });

```

Mongo or any span is not registered using express-session and Redis. Please check the [repository](https://github.com/ashrafuzzaman/apm-redis-session-test) for a sample case.

**Steps to reproduce** :

1. Please check the [repository](https://github.com/ashrafuzzaman/apm-redis-session-test)

**Errors in browser console (if relevant)**:  
Error in the terminal is provided

**Provide logs and/or server output (if relevant)**:  
Using redis as session store getting the following log,

```auto

    }
    transaction already ended - cannot build new span {

    }

But without the session store,

I later found that elastic APM node only supports Redis 2.0.0. I was using Redis client 3.X. This is really frustrating that APM don't support the latest version of Redis and creates issue if the latest version is being used.

Thanks for reporting and creating an [issue](https://github.com/elastic/apm-agent-nodejs/issues/1806) for this!
