REG: Traveled Route API

[AmarDK]

Im trying to fetch traveled route API.

cURL request for working condition
curl --location 'http://apis.mappls.com/advancedmaps/v1/*********************/still_image_polyline'
--form 'height="400"'
--form 'width="1024"'
--form 'polyline="[[ 77.65713468333334, 12.836220116666667 ],[ 77.65713493333334, 12.836227083333334 ],[ 77.65713623333333, 12.8362265 ],[ 77.65711906666667, 12.83621075 ],[ 77.65481075, 12.877442433333334 ]]"'
--form 'licence_key="fe4f164e99c5dcc440322f6b5ca7e384"'

In above cURL request -> polyline property if array doesn't contain whitespace its work perfectly.

In Javascript Array format is like this
"[ [ 77.65713468333334, 12.836220116666667 ],[ 77.65713493333334, 12.836227083333334 ],[ 77.65713623333333, 12.8362265 ],[ 77.65711906666667, 12.83621075 ],[ 77.65481075, 12.877442433333334 ] ]"

For above array format i will get error
{"code":400,"message":"Invalid polyline parameter"}
