Hi anyone, I have a question regarding th flow filters - I try to change the output with record_modifier, it works for some, but I haev problems with the syntax for nested records: I want to change the container.name like this:

- record_modifier:

records:

- container.name: ${record["kubernetes"]["container_name"]}

But as Output I just get NULL, so the expression is obviously wrong - but I couldn't figure out how to set it to the correct value...
