How to resolve deserialization error in delayed job?

Question

I am trying to use DelayedJob and the job is failing, giving the following error in the database:

{Delayed::DeserializationError
/Library/Ruby/Gems/1.8/gems/delayed_j         


        

Answer 1

Today, I also suffered through this error and after doing hectic analysis found:

1. delayed_job converts methods & parameters to YAML format and stores it into database
2. It can be found using select * from delayed_jobs;
3. deserialization error occurs when delayed_job is not able to deserialize it.

Probable causes can be:

1. args["xyz"] used before calling delayed_job & inside worker using it as args[:xyz]
2. Sometimes extra arguments passed along with object to delayed_job that time delayed_job fails to build object as it is indifferent access.

I Hope this will help!
