Recovery flow failing in email stage

[mmierke]

Describe the bug
I'm new to Authentik and tried to setup the recovery flow as described in the video of cooptainian.
However the flow is failing in the recovery email stage.

To Reproduce
Steps to reproduce the behavior:

1. Logout
2. Hit the "Forgot username or password" link
3. Fill in your correct email address or password
4. Press the continue button

Another way to reproduce it is to run the flow with the flow inspector

Expected behavior
A clear and concise description of what you expected to happen.
I would expect to receive an email to reset my password and to continue.

Screenshots
If applicable, add screenshots to help explain your problem.

Logs
Output from the events log after using the inspector
