get_available_fields() return empty list

[eLvErDe]

Hello,

It seems with the Opensearch API I'm trying to use, your module is not working.
If you're interrested in, you can reproduce the issue with the following snippet:

import pyops
client = pyops.Client(description_xml_url="https://mundiwebservices.com/acdc/catalog/proxy/search/Sentinel1/opensearch/description.xml")
fields = client.get_available_fields()
print(fields)

Regards, Adam.
