I am working on .Net Core 8 and HangFire 1.8.12 solution to run few recurring jobs. I have below code for interface

public interface IDatabaseMgtJobs
{
    Task<int> BackupMyDatabase();
}

and I have implemented this interface and added required DI code to startup class.

I need to schedule this method to run on daily basis and I have added below code to setup recurring job using Hangfire jobs

RecurringJob.AddOrUpdate<IDatabaseMgtJobs>("backupMainDB", (Expression<Action<IDatabaseMgtJobs>>)(mgt => mgt.BackupMyDatabase()), cronexp, TimeZoneInfo.FindSystemTimeZoneById("India Standard Time"), "database");

with this code, I am able to place a job to Hangfire server but when its time to run the job its failing with below exception.

Hangfire.Common.JobLoadException: Could not load the job. See inner exception for the details.

I am bit familier with HangFire Jobs, but not sure this time whats wrong with this code. Any suggestions ? thanks in advance !
