It looks like you don’t have dependency injection setup. The default job activator just uses Activator.CreateInstance as you can see in the stack trace.

Thanks for your advice

I have written the
service “BackgroundService” with injection (DbContext and PayamakServise )
and this backgroundjob :
" BackgroundJob.Enqueue(x =>x.BackgroundSendPayamak(“Rahyab”, Message, user.PhoneNumber));"

It displays on the dashboard hangfire job:
// Job ID: #42
using Nick.Service.DataAccessService.Background;
var backgroundService = Activate();
backgroundService.BackgroundSendPayamak(
“Rahyab”,
“hi”
Message
,
“PHONE_NUMBER”);

But it gives this error again:
System.MissingMethodException: No parameterless constructor defined for this object.

Thanks

after success job1
job2 is:
BackgroundJob.ContinueJobWith(jobEmail,() => UpdateProductNotification(item), JobContinuationOptions.OnlyOnSucceededState);
