Geojson names not imported

[ninoppp]

Maputnik version:newest
Browser: Firefox&Chrome
OS:Linux&Windows

Description of the bug:
I added a data source (json, url). The features from the source do indeed show up, but without the names they have in the geojson. Clicking on every feature shows undefined, while they have properties to them i.e. on geojson.io. This makes it impossible to use the filters I want
Steps to reproduce the behavior:

1. Add a data source,json(url). I used this one
2. Make a layer with the data source, fill.
3. Click on the visible layer

Screenshots:

Btw great software otherwise!

Thanks for taking the time to open this issue!
I belive the code is expecting tilejson file to know which layers to inspect, and geojson source has only "one" layer.
Maputnik is basically using maplibre-inspect plugin, any chance you could check if it has the same issue?

In order for the name to appear, please add a symbol layer to the style.

This style works for me: maputnik_issue_geojson_names_not_imported_#957.json

@zstadler okay, maybe I'm stupid and am using the filters wrong. Would you mind giving me an example, how I can filter so only features without "example1" or "example" in their names are dispalyed?

[zstadler]

No, you are not stupid. You just need to learn more.

Here is how you filter-out elements that have "Status unknown":

      "filter": ["==", -1, ["index-of", "Unknown status", ["get", "name"]]],

The expression ["index-of", "Unknown status", ["get", "name"]] searches for the sub-string "Unknown status" in the "name" field/property. If it is not found, the result is -1.
The filter is defined to accept only features that got a -1 result: elements that do not have "Unknown status" in their name.

An updated style file is attached.
