Bug fixes

You can now enable or disable TLS encryption for SMTP notifications about model monitoring. If your email server does not support TLS encryption, turn this off in the Notification Channels window.

Large numbers of jobs are now processed promptly, resolving a known issue where queued jobs were processed slowly when the total number of jobs was larger than the execution quota for the user or the hardware tier.

After you migrate from 4.x, scheduled jobs will fail until the users that own them log out and log in again. This issue is resolved in Domino 5.3.0.

Tip

Known issues

Workspaces become unstoppable and their statuses don’t change when the timestamps on the run’s status changes array are incorrect.

You cannot view the latest raw file. In the navigation pane, go to Files and click a file to view its details. If you click View Latest Raw File, a blank page opens.

After deleting branches that were created in GitHub but not pulled (that is, they are not local on Domino), they are still shown in the Code menu in the Data tab of the workspace.

If you are comparing jobs that have large numbers of output files, you might encounter a 502 Bad Gateway error.

In the Control Center’s navigation pane, click Assets. Domino displays a "Failed to get assets" message and takes a long time to load the assets.

You cannot delete, rename, or move a .gitignore file in a Domino File System project.
- If you delete the file, it remains.
- If you move the file, the original and target file both exist.
- If you rename the file, the source and renamed file both exist.

If you rerun a successful job that accesses files from a dataset in a project owned by an organization, the job fails with file not found errors. Initial runs of the jobs succeed, but reruns fail with logging similar to the following:
```
2022-10-06 04:34:32 : FileNotFoundError: [Errno 2] No such file or directory: '/domino/datasets/local/reruns_fail/file.txt'
```
To work around this, start the execution as a new job.

You cannot change the Visibility of a compute environment from Globally accessible to private.

If you use a forward slash (/) in a Git branch name, the forward slash and any preceding text is stripped. For example, if the branch was named test/branch1, it will be renamed branch1.
- In a workspace in a Git-based project, you can’t pull data because the branch doesn’t exist. You can push because this creates a new branch named branch1.
- In a Domino File System project that uses imported code repositories, you can push and pull directly to and from the branch (test/branch2) if you don’t change the branch in the menu. If you change the branch, you can’t return to the selection (test/branch2) because test/ is stripped. If you push to branch2, this creates a new branch named branch2.

The graph views are skewed incorrectly, in Domino’s model monitoring, when normalized values are small.

When exporting notebooks from JupyterLab workspaces, the system shows a 403 Forbidden Error with Blocking Cross Origin message.

Domino can become inaccessible after a fixed uptime period when running on Kubernetes 1.21 or higher. See this knowledge base article for the workaround. This issue is fixed in Domino 5.3.1.
When exporting notebooks from JupyterLab workspaces, the system shows a 403 Forbidden Error with Blocking Cross Origin message.

Upgrading to this release from Domino 3.x or 4.x can cause Git credentials to be omitted from the dropdown when creating a new Git-based project. A workaround is available from Domino’s Customer Success team.

When you use drag-and-drop to upload a large number of files at once, the upload might fail. The application displays many empty dialogs. Use the Domini CLI to upload large numbers of files instead. Domino 5.4.0 eliminates the empty dialogs and shows helpful information.

In a Git-based project, requirements.txt must be in your project’s Artifacts folder in order to be picked up by an execution, instead of at the root level in your project files.

Tip

Model Monitoring data sources aren’t validated. If you enter an invalid bucket name and attempt to save, the entry will go through. However, you won’t be able to see metrics for that entry because the name points to an invalid bucket.

A limit overcommit error (OOMKilled) is occurring frequently on the prometheus-adapter pod in Domino’s Integrated Model Monitoring. The current workaround is to increase the limits. This issue is resolved in Domino 5.5.0.
