Selectors give strange error when having 0 relevant entries (shopping basket client)
If I want to get entries for a specific collection from my shopping basket, I could use a connector. That would be done like this:
from shopping_client import shopping_client
from samp import samp_connector
esap_api_host = "https://sdc-dev.astron.nl/"
sampcon = samp_connector()
sc = shopping_client(host=esap_api_host, connectors=[rucicon, sampcon])
mydata = get_basket(convert_to_pandas=True)If I have samp data in my shopping basket, all is good. If I do not have samp data, the client will fail with:
