hey @Serhii Chvaliuk [GL] thanks a lot. But then what is the difference between this
configured_catalog.json
and what we define in
schema
subfolder
s
there are 2 similar things ‘catalog’ and ‘configured_catalog’
Copy code
python main.py discover --config secrets/config.json > catalog.json
this produce ‘catalog’
after that you need to “transform” catalog.json -> configured_catalog.json
