geolocation - Geocoding node-red-node-google. Error "Invalid request. Invalid 'latlng' parameter" -

i´m not expert in node-red , appreciate on using node-red-node-google geocoding node. link google geolocation node-red node

i'm trying obtain location address via google geolocation api obtained coordinates using node mentioned above (geocode coordinates option). take latitude , length via post external application.

how should latitude , longitude data fed geocode node correct address data? after tens of tests, obtain same error: "invalid request. invalid 'latlng' parameter". i'm doing is:

1. take data generated via post http://my_public_ip:1880/geo?id={device}&time={time}&lat={lat}&lng={lng}&radius={radius} first node of flow node-red http in node, implements htp end-point, gets info callback. te info retrieved correctly (see debug output) : {"id":"18a834","time":"1503231980","lat":"40.xxxxxxxxxxxxxx","lng":"-3.xxxxxxxxxxxxxx","radius":"1651"} note: coordinates shadowed privacy reasons.
2. if lng , lat values http in node fed google geocoding node, message error "invalid request. invalid 'latlng' parameter" received.

i fill dialog box way:

latitude text box: msg.payload.lat

longitude text box:msg.payload.lng

3. i have tried several options inserting coords function node: convert latitude , longitude values float, keep first 7 decimals, convert again strings ..., , same error received: "invalid request. invalid 'latlng' parameter"

the coords function node configuration:

var coords ={}; latitude= parsefloat(msg.payload.lat).tofixed(7); latitude1 = parsefloat(latitude); var length = parsefloat(msg.payload.lng).tofixed(7); var length1= parsefloat(length); coords.payload = {lat:latitude1, lng:length1}; return coords; 

the function output seems correct: {"lat":40.xxxxxxx,"lng":-3.xxxxxxx}

so expected fill text boxes msg.payload.lat , msg.payload.lng should ok. wrong ...

does know correct way feed longitude , latitude values node-red-node-google google-geocoding no errors? find below node-red used code (remember, tested different types of variable , tested no function @ all):

you shouldn't putting msg.payload.lat or msg.payload.lon in config dialog. if passing values in via message object need leave them blank in config dialog.

next, mentioned in readme.md , info bar in node-red, need set msg.location.lat , msg.location.lon on incoming message pass value node.

so function node should little bit more this:

var coords ={}; latitude= parsefloat(msg.payload.lat).tofixed(7); latitude1 = parsefloat(latitude); var length = parsefloat(msg.payload.lng).tofixed(7); var length1= parsefloat(length); coords.location = {lat:latitude1, lon:length1}; return coords;
