getting unprocessing fields status error while sharing on Linkedin from V2

[yamino2h]

Hi I am using this package and trying to share on LinkedIn from v2 api of Linkedin but I am getting following error

Unpermitted fields present in PARAMETER: Data Processing Exception while processing fields [/format]

I debug your code you guys are appending format=json in query parameter while making request url for share and that cause error, if I remove that query parameter its working fine

I cannot tweak into the vendors folders of you as I will composer update my changes will gone, so can you give some solution for this?

Thanks in advance
