Support added for allow list for LaxRedirectStrategy
Resolved in Pega Version 8.3.6
When using Connect REST with POST to access a third-party service deployed on multiple nodes, the load balancer sometimes replied 302 with Location header. The ability to allow the REST connector to automatically follow these redirects even in the case of POST messages is supported by Apache http client via LaxRedirectStrategy, but REST Connectors need both rule and engine enhancements to allow for this. To support this use, an allow list has been implemted for hostnames. This will allow the connector to be configured to follow the LaxRedirectStrategy only when the hostname of the redirect location is in the allow list. The default will continue to block the redirect.

Handling added for unknown ProducerID exception
Resolved in Pega Version 8.3.6
An "UnknownProducerIdException" was seen in the PegaRULES and Kafka broker logs for Stream services. This exception is raised by the broker if it can not locate the producer metadata associated with the producerId in question. This could happen if, for example, the producer's records were deleted because their retention time had elapsed. Once the last records of the producerId are removed, the producer's metadata is removed from the broker and future attempts to append additional metadata will return this exception. To resolve this, a new producer will be used if the old one is unknown.

Logging for MultiNodeSynchronize lock attempts changed from error to warn
Resolved in Pega Version 8.3.6
The File Listener was logging numerous errors stating "Unable to establish MultiNodeSynchronize lock while trying to determine if listener is enabled for this node". Handling has been previously established for error cases when the Listener is unable to establish a MultiNodeSynchronize lock, but this condition continued to be logged as an error even though it was not related to any failures in functionality. To resolve the logging issue, the logger level has been changed from ERROR to WARN.

MimeTypeHandler added for cloud downloads on mobile
Resolved in Pega Version 8.3.6
When using the Pega cloud storage repository (Application -> Integration -> Content Storage) with the Google Chrome browser on an android device, it was possible to upload attachments but re-downloading the attachments failed. Investigation showed that this was due to the content-type appearing as application/* so Chrome on mobile was not able to identify the file type. This was a missed use-case for returnFileForDownload(), and has been resolved by setting the system to use MimeTypeHandler for getting the content type.

Data Type local data storage snapshot history updated
Resolved in Pega Version 8.3.6
When a History Class Data object was created, two snapshots were made - one with value and another with no value. This was traced to a 'when' condition that evaluated whether to add history when deleting a record from records editor, and this issue has been addressed by removing the condition as the history-add step takes care of checking if there is a dedicated table or not.

S3 attachment migration handles LInk-Attachment with multiple instances
Resolved in Pega Version 8.3.6
After S3 attachment migration, some attachments were intermittently not opening and displaying an error relating to being unable to load the file. Investigation showed that the attachments that failed to open did not have a pxStorageType tag in the XML of the work item. After the migration is done, the corresponding Data-WorkAttach-File and Link-Attachment instances are updated to point them to the repository. In this case, multiple LInk-Attachment instances were pointing to the same Data-WorkAttach-File instances, so only one Link-Attachment was updated and all of the other instances pointing to the same Data-WorkAttach-File instance were rendered unusable. While there was a workaround of manually updating the storage type in the database, this has been resolved by updating "pzgetattachmentcontent","pzupdatesourcereferences", and "pzuploadcontenttoexternalstorage" to check whether attachment is already migrated or not using the boolean parameter "isAttachmentAlreadyMigrated" to ensure all of the other Link-Attachment instances for a particular attachment are updated. If a migration was done and all Data-WorkAttach-File instances are pointing to a repository with some Link-Attachment instances not updated, those will be updated by running the migration again.

REST connector creation errors resolved
Resolved in Pega Version 8.3.6
Attempting to create REST Connectors via the dev studio wizard using live endpoint invocation as "Add a REST response" was failing with a java.util.LinkedList error. This had a workaround of either running the REST wizard with file upload samples or configuring them directly on the rule form. In addition, REST Connectors were not executing if both the DEBUG level logging was turned on and the request had no headers, which had a workaround of using any other logging level (INFO, ERROR). These issues have been resolved by updating the system such that pyResponseHeaders are populated appropriately, and if there are no headers in the request, the system will not try to remove the trailing comma that would have been introduced in the oLog message.

Traffic handling added for offline pod condition
Resolved in Pega Version 8.3.6
If one of the pods in a cluster went down and failed to restart by itself due to Hazelcast Cluster rejoining issues, there were intermittent issues of non-availability of the system. Investigation showed this was due to traffic being routed to the broken pod because the health check returned a false positive. This has been resolved by adding an update to return failed status when the exception "java.lang.IllegalStateException: Cluster has not started or is not fully initialized." is encountered.
