NAV 2018 RTM Job Queue - Enqueue - Scheduled task record created, but never executed

Sog

During tests of creating a job queue entry via codeunit 453 Job Queue - Enqueue via a webservice running under a super account, I notice the following behaviour:
Job queue entry is created, status is set to ready and has a system task ID.
In the table Scheduled Task, I see a new entry being created under the account calling the web service.
A moment later the entry is removed (possibly because the task scheduler picked it up), but the job queue entry remains untouched.
Job Queue's scheduled is set to "No", the corresponding system task id has been removed.

When running the same code via a client session, everything behaves as normal, but when it's a web service session, the described behavior is showing.
Has anybody run into this issue?
Web service is of the SOAP kind, did not test this with ODATA

Are you using the same "super account" to test the job queue via the client session?

And after plowing through a lot of scenarios, it appears it's an NAV 2018 RTM bug resolved in the CU1. See here: cumulative-update-01-for-microsoft-dynamics-nav-2018 item number 253071

So a CU 1 upgrade is required for a correctly functioning job queue in various scenarios. What I did notice is that even when the NETWORK SERVICE was directly logged into the rtc, the issue persisted.

I did not expect that to be an issue, but you're correct Slawek. Changing the calling user account to my owndid make it work. Now I have to figure out why the other user account couldn't schedule the task. (which was NT AUTHORITY\NETWORK SERVICE) I know it shouldn't be a super user, but this of course isn't a production environment.

my case is similar like this case below

"Job queue entry is created, status is set to ready and has a system task ID.
In the table Scheduled Task, I see a new entry being created under the account calling the web service.
A moment later the entry is removed (possibly because the task scheduler picked it up), but the job queue entry remains untouched.
Job Queue's scheduled is set to "No", the corresponding system task id has been removed."

The issue still appears on a test environment in CU1. After changing the calling user of the webservice to a domain user, the issue disappeared. We still need to execute more tests, but what we found out is that under network service, tasks cannot be scheduled under some scenarios

I am using nav 2018 CU 03, if the service starts using network service, then it cant run job queue.
but if using domain account then it can run...
my 2017 edition no issue either using network service nor domain account
