How to scrape JSON embeded in script tag at HTML?

[hkcomori]

I want to get the new posts from the JSON embedded in the following site.
Is that possible with FreshRSS?

I tried scraping with JSON dotpath but failed.

url: https://comic-walker.com/detail/KC_003631_S?episodeType=latest
id: __NEXT_DATA__

<!-- some html -->
<script id="__NEXT_DATA__" type="application/json">
    {
        "props": {
            "pageProps": {
                "workId": "018d6a65-6bb2-79b0-8a26-d248741e2c22",
                "workCode": "KC_003631_S",
                "episodeType": "latest",
                "dehydratedState": {
                    "mutations": [
                    ],
                    "queries": [
...
</script>
<!-- some html -->

I don't think that's currently possible given that you'd first have to retrieve the JSON from that element.

Indeed, this is not something natively supported by FreshRSS at the moment, but options include making your own FreshRSS extension, or RSS-Bridge bridge.

Thank you. I still haven't achieved my goal, but I understand the approach.
It's necessary to extract the JSON by preprocessing with an extension or other tool before subscribing with FreshRSS's JSON dotpath, right?
Unfortunetly, I couldn't process it as JSON in FreshRSS because RSS-Bridge escapes the extracted results.
I will try to find another way.
