I can't get the lat-lng array from a geoJson as expected (coordsToLatLngs)

[Rossana Guerra]

Hi, I need to get the latitude and longitude from a multilinestring geojson file in order to store them.  

I can get the array, but when I want them to convert to the lat, long format I got the error "is not a function"

This is the part of the code that isn't working.

function onEachFeature(feature, layer) {
 layer.on({
 mouseover: highlightFeature, //defined above -> it works
 mouseout: resetHighlight,
    click: zoomToFeature
    })
    latlngBiciSendas.push(feature.geometry.coordinates);        // Array
}

function resetHighlight(e) {
     geoBS.resetStyle(e.target);
}


function loadBS()
{


    geoBS = L.geoJson(bicisendas, {
       style: style,
      onEachFeature: onEachFeature
            
    }).addTo(mapa);
 
    L.geoJson.coordsToLatLngs(latlngBiciSendas,1,true);  <- this function is the problematic one.

 alert(latlngBiciSendas.length); The array is loaded correctly
 
};

In order to pass apply this array to an argument to some functions I need to "reverse" the array, i.e: put in the lat, long order.
I recall I am new to javascript and leaflet as well, I was trying and searching without luck. I don't know if I have syntax errors or the conceptual ones.

Error message: Uncaught TypeError: undefined is not a function 

I appreciate any help, thanks

Thanks Benedetto, I am sure that it isn't empty at the begining.
Secondly, I already had seen the link you posted, but it seemed it couldn't fit to my problem. 
My geojson is multinestring, so corrdinates[1] it didn't give what I expected.
As soon as I have time, I'll try to post my original code. 
Best!
