geo shape json object support ?

[arun-pal2018]

Can I get help for creating json object for geo shape. When tried to create json object for geo shape "polygon" with coordinates [[ [ 4.92, 52.40 ], [ 4.92, 52.30 ],[ 5.02, 52.30 ], [ 5.02, 52.40 ], [ 4.92, 52.40 ]]]. The ejson is throwing error :
** exception error: no case clause matching {error,"coordinates",throw,
{invalid_list_item,[[4.92,52.4],
[4.92,52.3],
[5.02,52.3],
[5.02,52.4],
[4.92,52.4]]}}

The json document format is given below:
-json({document, {record, "geo_shape"},{string, "tag"},{ string, "geo_address"}}).
-json({geo_shape_location, {string, "type"}, {list, "coordinates"}}).
