Geoip error (expected database)

Hello,
I have installed elasticsearch 7.4.2. I want to use the geoip processor. The documentation says I need to download and copy the geolite DB into dir /etc/elasticsearch/ingest-geoip
https://www.elastic.co/guide/en/elasticsearch/reference/7.4/geoip-processor.html

Once I have done this startup of elastic fails:
java.lang.RuntimeException: java.io.IOException: expected database [GeoLite2-City.mmdb] to not exist in [/etc/elasticsearch/ingest-geoip]

How to enable geoip with elasticsearch? Can anybody please assist?

Thanks in advance.
