"Bad request for URL" when running "prefect get flow-runs"
## Description
I see the following error when running `prefect get flow-runs`:
```
Traceback (most recent call last):

```

The same error occurs if I specify a flow (`--flow`) or project (`--project`). 

I'm running 0.13.11. The version of prefect matches the tags of the running prefect containers.

## Reproduction
On a VM:
```
pip3 install prefect
prefect backend server
prefect server start
```
Wait for images to download and the services to start. Then run:
```
prefect get flow-runs
```
