Ah, I think this is a bug in the latest update. Try the following:

```auto
chown -R pioreactor:www-data /home/pioreactor/.pioreactor/storage
chmod -R 770 /home/pioreactor/.pioreactor/storage

```

and then try:

```auto
curl localhost/unit_api/calibrations | jq

```

If you see an error again from that `curl` command, try `pio logs` and lmk what you see there.
