**Additional context**
Seems to come from OWSLib, possible the version is outdated?
Version:
`OWSLib==0.20.0`

OWSlib is now at `0.26.0` with OGC API - Records 1.0
https://geopython.github.io/OWSLib/usage.html#ogc-api-records-1-0 - support.
But simply increasing the version number has challenges because of existing work-arounds in the OGCFeat Probe Python code for early OGC API versions.
