Matrix/Vector 'entries' has length of 0

Hi,
I could get the python script running , but my script returns x = 0

```
import dsbapi

dsbclient = dsbapi.DSBApi("1*****", "********")
entries = dsbclient.fetch_entries()

x = len(entries)
print(x)

for s in range(len(entries)):
  for i in range(len(entries[s])):
    print(entries[s][i]["date"])
    
print("end")
input()
```
@LenniMaxMine can you help? :-)
