Amphtml: WARNING in G console : "The script tag contains invalid JSON that cannot be parsed"

[abhiz10]

Hi AMP Team,

We are getting a WARNING in G console: "The script tag contains invalid JSON that cannot be parsed"

Ref: https://nature.visualstories.com/paper-recycling-process

But when we validate the above JSON there is no such warning or error reflecting.

We're experiencing the same exact problem. Google Search console returns this warning:

    "The script tag contains invalid JSON that cannot be parsed"

but validation is successful and no warnings or errors are returned. Google console highlights all amp tags containing JSON like

    <amp-geo layout="nodisplay">
           <script type="application/json">
           {
               "ISOCountryGroups": {
                     "eea": [ "at", "be", "bg", "cy", "cz", "de", "dk", "ee", "es", "fi", "fr",
                          "gb", "gr", "hr", "hu", "ie", "is", "it", "li", "lt", "lu", "lv", "mt", "nl",
                            "no", "pl", "pt", "ro", "se", "si", "sk"]
                  }
            }
           </script>
</amp-geo>

The warnings showed up just a couple of days ago, even though the pages were the same as before, no changes, Maybe a bug in some new version of the validator used by Google console?

Exact the same problem here. 13.000 pages with warnings since yesterday.

This same issue is happening at https://amp.magnetjewelrystore.com/allssgend.html and dozens of other AMP pages on the same domain.

Note, this is just a warning.

Removing all newlines in the the application/json - Tags solves the problem for me.

Now, it's not showing any WARNING ....Thanks

This is being reported as a warning in search console and has no impact on your appearance in search. The issue has already been resolved, but your pages will need to be re-indexed before the warning will disappear.
