Error building locally

First of all - Im a reaaaally big fan of the project and would even like to donate and or contribute to the project.

Unfortunatly my programming skills are medium at best, so following Problem occured:

I wanted to build a local docker image with the newest version (Im looking forward to use the api for automatic upload) but I wasnt able to build successfully. Following is the beginning of the error: Could someone maybe point me in the right direction on how to fix this - I would love to use the api...

Kind regards

```
1913.7 error[E0599]: no method named `into_response` found for struct `templates::Client` in the current scope
1913.7 --> crates/tf-auth/src/routes/client.rs:29:23
```

Reproduce the local Docker image build and begin with crates/tf-auth/src/routes/client.rs at line 29, then inspect the surrounding templates::Client and into_response error. Done means the newest version builds successfully in Docker and the reported API build path is usable.
