Errata Report for Release v2023.1.1

The following are known issues in our latest release

Firefox browser compatibility

Current Behavior

Unexpected crashes and rendering are noticed on Firefox.

Workaround

Chrome is the currently recommended browser. We will bring support to Firefox in one of the future releases.

Analytics Screen Refresh

Current Behavior

Online/Offline connection status on stream window is not updated immediately.

Open

Workaround

Wait for 30 sec or refresh the page.

Use Case Commissioning Error

Current Behavior

When a use case commissioning action errors out, the program currently tries indefinitely to auto-restore it. This might lead Nimble to end up in an unfavorable state.

Workaround

When use case commissioning errors out, please delete the errored out use case and re-deploy manually with the error rectified.

High Latency During Network Congestion

Current Behavior

Nimble may buffer up to, by default, 30 frames per channel before dropping data. When the network is congested these buffers may fill up causing high latency.

Workaround

Update the environment section of the docker-compose.yaml file to specify the following variable:

Setting the queue size to 30 will add a maximum of 1 second of latency for a 30fps channel or 6 seconds of latency for a 5fps channel during network congestion. For sites with network congestion it is recommended to set this value to 5.

Mismatch in analytics count for most of the use-cases

Current Behavior

In the event history, the count seen in table is not the exactly same when the images are retrieved.

Workaround

No workaround, will be fixed in next release.

Storage Purge trigger is not deactivating the alert

Current Behavior

Triggering storage purge of a particular channel is not deactivating the activated alert of that channel.

Workaround

No workaround, will be fixed in the upcoming release.

Site Reports Notifications list shows notification count as 0

Current Behavior

Site Reports table shows the total notifications count as 0 even though there are notifications that are being sent.

Workaround

No workaround, will be fixed in the upcoming release.

Missing Post Usecase is not supported with On demand feature.

Current Behavior

Missing Post will only receive one notification when there is switch from having detections to a blank frame with no bounding boxes in the video stream. Repeated notifications don’t get sent as long as video frames are empty when on demand feature is on.

Workaround

No workaround, will be fixed in the upcoming release.

Vas Portal Install command fails during Portal installation.

Current Behavior

While installing the vas-portal using the mcutils command i.e. mcutils install vas-portal, the installation fails sometimes.

Workaround

Please run the vas portal installer command again, this will install the portal successfully.

Creating and activating of rules with multiple alerts is not supported

Current Behavior

Contextual rules consisting of multiple alert conditions using AND, OR is not supported. In the current release, the combined/composite rule is an experimental feature not guaranteed to work with all combinatorial logic reliably. Currently its recommended to create rule consisting of single alert only.

Workaround

No workaround, this feature will be stabilized in the upcoming release.
