Tasks never running

**Steps to reproduce:**
List the minimal actions needed to reproduce the behavior.

1. Create a task
2. Save it
3. Click on gear icon > view task runs
4. Click view logs

**Expected behavior:**
Task is scheduled, starts and runs. Gives meaningful feedback in logs.

**Actual behavior:**
Task is scheduled, but never starts or runs. Attempting to view the logs shows an error page with "An InfluxDB error has occurred. Please report the issue here."

**Environment info:**

- System info: Linux 5.8.0-55-generic x86_64
- InfluxDB version: InfluxDB 2.0.7 (Server: 2a45f0c, Frontend: 217d8c0)
- Other relevant environment details: Running on kubernetes cluster.

The same tasks run as expected a previously used older version:
- InfluxDB version: InfluxDB 2.0.4 (git: 4e7a59bb9a)

**Logs:**

Attempting to access runs through postman with `api/v2/tasks/07dbe8e129768000/runs` returns
