The following code can reproduce the problem:
```python
from ipapython import session_storage

CCACHE_COOKIE_KEY = "X-IPA-Session-Cookie"

principal = "admin@IPA.TEST"
data = "test"

session_storage.remove_data(principal, CCACHE_COOKIE_KEY)
session_storage.store_data(principal, CCACHE_COOKIE_KEY, data)
print(session_storage.get_data(principal, CCACHE_COOKIE_KEY))
```

output:
