question on json parsing.

[RXWatcher]

Hi,
I'm trying to parse this: https://oap.ind.nl/oap/api/desks/DH/slots/?productKey=BIO&persons=1

It has garbage on the first row so I place this in the ignore text under filters: )]}',

It should now be a valid json and if I use json linters with everything below that line, it comes back as valid.

I'm trying to use this as a filter: json:$.data.*.date,startTime which if I run it on https://jsonpath.com/ against the output of the website without that garbage produces what I'm looking for.

changedetection.io is throwing a 'No parsable JSON found in this document'.

Am I doing something wrong with my flow?

Do you have any suggestions to get around the garbage on the first row for parsing?

I am trying with Playwrite Chromium.

Thank you!
