Hi nabheet madan
I recreated this issue in my system and I was also getting same error.
On further debugging, I found that the error comes from class /IWWRK/CL_WF_READ_WORKITEM in the method READ_ITEM_VALIDATION.
Internal table mt_wi_wapi_agents is read with sy-uname.
This internal table  mt_wi_wapi_agents is getting filed by FM SAP_WAPI_GET_WI_AGENTS in other method within same Class.
I checked with below workflow id which are there in my inbox. 2 are in In Process status and one is in Ready status.
so the items which are in 'In Process' status will get approved as per standard logic. and to make the item which is in Ready status to In process, We need to execute it in SWBP inbox and then need not to approve/reject as mentioned in earlier response.
I do agree with you that even items which are in Ready status should be processed without error but this is how the validation logic is there in standard method.
