问题 I've a error thrown I can't figure out how it happens. It doesn't occur all the time but once in a while.

I've used connectionRequest for parsing the json data. When the error is thrown I've checked if there's problem in url but it gives the proper json data as always. After trying few times, the error is solved

The user needs to execute some external action on device
