Script failure ‘ReservationUpdateException’

Hi there,

We had an issue were after attempting to run a script we saw the following failure message: Skyline.Dataminer.Library.Exceptions.ReservationUpdateException: Reservation named XXXXX wasn't updated successfully.

I can see this error in the SLAutomation log but I would like to continue to trace this through and would like some advice on what logs I could potentially check next to see why this reservation change for a booking failed to update?

Hi Philip, do you have the exception full stack trace? If so, can you post, should already contain some information of what happened

Hi Philip,

You should be able to get more details on this in the resource manager logging.

Hi there we had the failure again and we werent able to find any errors at the same time in resource manager but we were able to find errors in the booking manager.

Hi Philip,

The important parts of the error are:

SLDataGateway.API.Types.Exceptions.Queries.QueryException: Exception thrown while executing paged query:
Query(((ReservationInstance.End[DateTime] >=01/22/2026 15:28:26) AND (ReservationInstance.Start[DateTime] <=01/22/2026 15:28:26)) )

Elasticsearch.Net.UnexpectedElasticsearchClientException: The operation has timed out. —> System.Net.WebException: The operation has timed out.

This shows that the system was unable to fetch the required data from the database within a reasonable time.

Since the database is the root cause of the problem here, you'll have to take a closer look at the database logs (the elastic or opensearch logs) and the database server health metrics, like load, memory usage, etc.

If you need more assistance to investigate this, please reach out to support@dataminer.services
