Bug in requeuing?

bug?
1

I have a job which takes a user defined object as one of the parameters. Hangfire is able to queue and trigger the job when everything is working normally, however if the job throws an exception and Hangfire requeues it, it will always fail to start the job with this error:

(Where obviously Full.Class, Assembly Name etc is the replaced with the real name of my class)
