You re probably passing null value if you re loading the coordinates dynamically  set a check before you call the map loader ie  if mapCords  loadMap

Uncaught InvalidValueError  setPosition  not a LatLng or LatLngLiteral  in property lat  not a number   Means you are not passing numbers into the google maps LatLng constructor   Per your comment     Information from chromium debugger trader  Object     geo  Object         lat   49 014821          lon   10 985072        trader geo lat and trader geo lon are strings  not numbers  Use parseFloat to convert them to numbers   var myLatlng   new google maps LatLng parseFloat trader geo lat  parseFloat trader geo lon

I was having the same problem  the fact is that the input of lat and long should be String  Only then did I manage   for example   Controller    ViewBag Lat   object Lat ToString   Replace              ViewBag Lng   object Lng ToString   Replace              View - function javascript   lt script gt      function initMap             var myLatLng     lat   ViewBag Lat  lng   ViewBag Lng               Create a map object and specify the DOM element for display          var map   new window google maps Map document getElementById  map                          center  myLatLng              scrollwheel  false              zoom  16                         Create a marker and set its position          var marker   new window google maps Marker               map  map              position  myLatLng               title   Blue                     lt  script gt    I convert the double value to string and do a Replace in the     to     And so everything works normally

I had the same problem  and resolved it  In my case it was error due to the non-proper format  Please check the first and last coordinates array in geometry coordinates they must be same then and only then it will work  Hope it may help you

I had the same problem when setting the center of the map with map setCenter    Using Number   solved for me  Had to use parseFloat to truncate the data   code snippet    var centerLat   parseFloat data lat  toFixed 0    var centerLng   parseFloat data long  toFixed 0    map setCenter         lat  Number centerLat         lng  Number centerLng

I had the same problem with exactly the same error message  In the end the error was  that I still called the maps v2 javascript  I had to replace    lt script src  http   maps google com maps file api amp amp v 2 amp amp key                       type  text javascript  gt  lt  script gt    with   lt script src  http   maps googleapis com maps api js key                      amp sensor false  type  text javascript  gt  lt  script gt    after this  it worked fine  took me a while  -
