JsonPath Macth in new ready api version 1.5.0

Hi,

I updated the ready api for version 1.5, but my tests started to fail.

I have a datasorce exel where I am getting the value for "exceptect result" in JsonPath macth.

If my JsonPath doesn´t existe i put value "null".  

The 1.4 version works, but in version 1.5 returns the following exception

Any suggestion??

Thanks.
