The filter is working on the ImageMetaProps object hydrated from the 
json serialized string in the request_specs.spec column, which 
unfortunately makes fixing this a bigger pain in the ass since it's not 
a simple SQL update statement.

If I were you I'd probably just revert 
https://review.opendev.org/#/c/531347/ so you can get on with your Rocky 
upgrade while we deal with fixing the issue long-term upstream, either 
by reverting that change upstream as well or adding a compat shim in the 
ImagePropertiesFilter.
