Installation wizard after docker deployment (podman)

Hello,
I've deployed akaunting like described in here: https://github.com/akaunting/docker#usage
Running with rootless podman. I see no errors so far in the container logs. After `AKAUNTING_SETUP=true podman-compose up -d` I see the installation wizard in the browser but when opening the browser inspector, I also see some errors when filling out the form, trying to add currencies etc. like:
```
[Error] Failed to load resource: the server responded with a status of 419 () (companies, line 0)

promiseEmptyOnRejected (wizard.min.js:1:17596)

```
Adding a currency is also not possible at all. Any suggestions?
