Popup < node entity via ajax > broken

Thanks for reporting this @fonant
BUT I cannot reproduce the this Bug you report.

This Leaflet Demo View Page:
https://www.geodemocracy.com/drupal_geofield_stack_demo/web/geoplaces-ma...

is indeed using:

Drupal Core: 10.2.2
Drupal Leaflet Version: 10.2.18

and < node entity via ajax > as Leaflet View Popup settings (screenshot attached),
and it doesn't report any Leaflet Popup functional issue (even in its inspector).

The issue you report doesn't look like a general Leaflet module bug, but might depend by/from you specific Drupal app instance configuration ...

Closing this as "Cannot Reproduce".
Please reopen ONLY if you find (and can prove) evidence of a general Leaflet module Bug on this functionality.

Regards.

More information, although I haven't narrowed down the symptoms enough yet:

I have a map that has working popups in the node view page (it's a View Reference field), that fails in exactly the same way when I edit the View (without making any changes) and try to get the popups in the View Preview.

Working:

• Leaflet map view, added to Node display as a View Reference.
• Map displays entity references from four different Node reference fields from the current node.
• Four contextual filters using "Content ID from URL" defaults for "When the filter value is NOT available".
• Popups loading content using "< node entity via ajax >".

Fails:

• Edit the above View.
• Enter the NID four times in the Preview arguments (e.g. 1234/1234/1234/1234).
• Click on a marker in the Preview: popup appears for an instant then disappears. Same error as in summary.

Could it be that the AJAX mechanism needs the page to be for a node?

The other maps that break with "< node entity via ajax >" are those for a View that's not embedded in a node display.

These views used to work in previous versions of Leaflet and Drupal. Only broke in the last few days.

Hmm... another difference I've found:

The maps that fail to open popups contain an additional command in the AJAX returned:

    {
        "command": "add_css",
        "data": [
            {
                "rel": "stylesheet",
                "media": "all",
                "href": "\/core\/themes\/claro\/css\/classy\/components\/node.css?sfkw3v"
            }
        ]
    },

whereas the maps the work only contain the popup HTML insert command:

    {
        "command": "insert",
        "method": "replaceWith",
        "selector": "[data-leaflet-popup-ajax-entity=\u0022node-2294-map_popup_balloon-en\u0022]",
        "data": "<pop-up-html-here>",
        "settings": null
    }
