JSON to MAP Conversion

Hi all,

Im converting  a JSON response into a MAP so that i can iterate through the map for the values.

Im using RetailCommonWebAPI::getMapfromJsonString() in AX 2012 R2.

It works fine in JOB and normal classes.

But when i call the same in SysoperationFramework it throws the below error

"Object must implement IConvertible".

My sample json string is

{"Name":"TEST","Phone":{"AIR":"1","AIR2":"2"}}.

The error occurs at RetailCommonWebAPI::getMap() line number 11.

Thanks in Advance.
