Error while queueing an email with Sidekiq

Question

When sending an email with sidekiq as a queue using deliver_later. I'm getting this error:

ActiveJob::DeserializationError: Error while trying to deserialize arguments: fe_sendauth: no password supplied

The exact same email is sent without any problem using deliver_now in the console.

Any thoughts?

Answer 1

The RACK_ENV environment variable is needed (besides RAILS_ENV).

So, for production:

export RACK_ENV=production

Answer 2

fe_sendauth: no password supplied is an auth error from postgresql. When you enqueue a job which receives as a parameter a model it will serialize the object using globalid (something like "gid://app/Person/1") and when it tries to run the job it will deserialize the job (will basically do Person.find(1)). From the server where you have your workers running you cannot connect to the database with the given credentials.
