Correct line numbering on parsing error in log

[matsekberg]

Is your feature request related to a problem? Please describe.
When having parsing errors in the page jsonl it is very nice to be able to look in the serial log and find out what line the error is on.
It seems as if blank lines are skipped and the line number references are wrong if the file contains blank lines.

Describe the solution you'd like
When parsing, do count the blank lines also.

Describe alternatives you've considered
Sorry no other options :)

Additional context
Nope

The parsing happens object by object, so it is actually the object number instead of line number.
The library doing the parsing doesn't report on blank lines, only on JSON objects encountered.
I'm not sure if showing the object number instead of line number is more helpful...
