How to enqueue a repository method using hangfire which takes an object as an argument and calls on controller as an post method

I am using .net core web API to call the repository method in my controller to do the job in the background.
My repository method takes an object as an argument.
I am using BackgroundJob.Enqueue(UnitOfWork.TransactionRepository.BulkInsertManualTransactions(objTransactionsImport));
but it is throwing exception in dashboard of hangfire.
i have attached the screenshot for a reference
