2023.4.2

Release date: 1 September 2023

We have released a new version of the UiPath.OrganizationMigrationApp tool so that you can easily migrate from a standalone UiPath® product to Automation Suite. For details, see Migration prerequisites.

Release date: 10 August 2023

New RHEL version supported

You can now install Automation Suite on machines running Red Hat Enterprise Linux (RHEL) 8.8.

Important:

RHEL kernel version kernel-4.18.0-477.10.1.el8_8 is affected by an issue that interrupts the installation or management of the Automation Suite cluster. Make sure that none of the Automation Suite nodes uses this kernel version either pre- or post-installation. You can update the kernel version by running the following command:

dnf install -y kernel kernel-tools kernel-tools-libsdnf install -y kernel kernel-tools kernel-tools-libs

New alerts for Longhorn backup and snapshot objects

We have introduced new alerts so that you can monitor the number of backup and snapshot objects that Longhorn creates in the system. The following alerts are triggered when the aforementioned number is too high:

LonghornBackupObjectThresholdExceededWarn
LonghornBackupObjectThresholdExceededCritical
LonghornSnapshotObjectThresholdExceededWarn
LonghornSnapshotObjectThresholdExceededCritical

For details on the alerts and the script you can run to fix the issue that triggered them, see Alert runbook.

Improved Support Bundle Tool

We have made multiple improvements to the Support Bundle tool so that you can easily collect logs when troubleshooting Automation Suite:

The default number of days for the RKE and UiPath® bundles has been reduced to 2;
The RKE bundle generation is now disabled by default. To enable it, run the support-bundle.sh -r command;
Long-running commands in the RKE bundle are now disabled. To enable them, run the scripts/rke2-support-bundle.sh -a command;
It is now possible to disable Redis bundle generation by running the support-bundle.sh -s command.

Security enhancements

We continue to provide security updates and patches to address Common Vulnerabilities and Exposures (CVEs).

Bug fixes

When you enable a backup, we now validate the NFS server connectivity with all the nodes. Previously, we only checked the node from which you enabled the backup.
We have fixed the network policies previously preventing Document Understanding from setting the CORS policy for the internal objectstore and causing the installation to fail.

Attention: Due to a mishap on our side, we incorrectly marked this bug as fixed. This behavior still occurs in 2023.4.2, and it was fixed in 2023.4.3.
A network policy was preventing DNS resolution from happening. We have fixed the issue.
Previously, both scheduled and on-demand backups would fail after one hour of timeout. Now you can extend the timeout interval to three hours. For details, see Enabling the snapshot backup and On-demand snapshot backup.
On some occasions, the configureUiPathAS.sh script did not properly update or read the ODBC connection strings. This behavior no longer occurs.
Previously, when uipath-service-rook-ceph-secret was deleted or its fields were updated, recovery was not possible. Now re-running the credential manager job recreates the secret and reverts the fields to their original values.
The minLevel NLog setting in the config map was not being honored. The default minLevel is "Info" indicating that logs of "Info" severity and above should have been logged. However, the minLevel was not being considered, and logs with lower severity levels, specifically "Trace" and "Debug", were also being written to the logs.
We have updated the NFS disk requirements from 4 TiB SSD to 2 TiB SSD. The current requirement has been in place for some time now, but we missed documenting it.

Known issues

Erratum - added October 17, 2024: In a proxy environment, if the proxy server uses the same port as the TCP port of any other service in the Istio service mesh, such as port 8080, pods cannot communicate with the FQDN. The issue causes the following error:
```
System.Net.Http.HttpRequestException: The proxy tunnel request to proxy 'http://<proxyFQDN>:8080/' failed with status code '404'.System.Net.Http.HttpRequestException: The proxy tunnel request to proxy 'http://<proxyFQDN>:8080/' failed with status code '404'.
```
To fix the issue, see the Troubleshooting section.
Erratum - added August 29, 2024: We have identified certain vulnerabilities associated with the usage of weak ciphers in TLS 1.2. For details on how to mitigate the issue, see How to address weak ciphers in TLS 1.2.

Erratum - added August 14, 2024: An issue affects the support bundle generation when using an external OCI registry in an offline environment. Under these conditions, the generated support bundle lacks historical logs and cannot upload to any selected external object storage. To fix this issue, see the Troubleshooting section.
Erratum - added August 14, 2024: For AI Center and Task Mining, the ListBucket API prerequisite check fails when using an external objectstore. However, AI Center and Task Mining do not use the ListBucket API permission. We removed the unnecessary check in Automation Suite 2023.4.8.

Erratum - Added June 25, 2024: When generating the support bundle, an incorrect FQDN is used for AKS on Azure Government. We have fixed the issue in Automation Suite 2023.4.7.
Erratum - added May 20, 2024: On single-node deployments with in-cluster storage, upgrades from version 2022.4.1 or older fail at the fabric stage due to a rook-ceph migration issue. To prevent the issue, follow the instructions in this troubleshooting article: Single-node upgrade fails at the fabric stage.
Erratum - added April 19, 2024: In certain situations, Prometheus pods can fail to start due to an out-of-memory (OOM) error. To fix the issue, see the Troubleshooting section.
Erattum - added April 19, 2024: Alert configurations (email and webhook receivers) get lost on reboot of machine or re-sync of alertmanager-config secret. For details, refer to

Persisting Alert Manager configurations during machine reboot.
Erattum - added April 19, 2024: In certain situations, Ceph metrics and alerts are missing from the monitoring dashboards. To fix the issue, see the Troubleshooting section.
Erattum - added April 19, 2024: False positive CephMgrIsAbsent alerts are displayed even though there are no storage issues.
Erratum - added February 28, 2024: Stored procedures do not support collation differences between the SQL server and SQL database. To avoid any potential problems, you must ensure that the collation settings of both SQL server and SQL database are identical.
Erratum - added January 2024: The replica cleanup script incorrectly reclaims storage on the nodes. For more details, see the Storage reclamation patch troubleshooting article.
Erratum - added November 6, 2023

In versions 2023.4.0 through 2023.4.2, if you have an Active Directory (AD) integrated environment, you will see sporadic failures from the product leading to the IIS application pool restarting. This issue has been fixed in version 2023.4.3, but it still affects the aforementioned versions. As such, if you use AD, we highly recommend that you directly install or upgrade to 2023.4.3. Otherwise, you will encounter functionality issues.
The installUiPathAS.sh interactive installer tries to download as-installer.zip and fails in offline environments. To bypass the download step and prevent any installation issues, run the following command:
```
export BUNDLE_FILE="/opt/UiPathAutomationSuite/as-installer.zip"export BUNDLE_FILE="/opt/UiPathAutomationSuite/as-installer.zip"
```

During installation, the proper RBAC configuration is not applied, which results in issues accessing the ArgoCD read-only account. If you encounter this problem, use the following workaround:

kubectl -n argocd patch cm argocd-rbac-cm -p '{"data": { "policy.csv": "p, role:uipath-sync, applications, get, */*, allow\np, role:uipath-sync, applications, sync, */*, allow\ng, argocdro, role:uipath-sync\n"}}'kubectl -n argocd patch cm argocd-rbac-cm -p '{"data": { "policy.csv": "p, role:uipath-sync, applications, get, */*, allow\np, role:uipath-sync, applications, sync, */*, allow\ng, argocdro, role:uipath-sync\n"}}'

Deprecation timeline

We recommend that you regularly check the deprecation timeline for any updates regarding features that will be deprecated and removed.
