Null check added for step page
Resolved in Pega Version 8.3.6
After creating and adding new Access Roles and application 'Access When' to the privileges instead of Production level, during run time the error "runtime.IndeterminateConditionalException: Trying to evaluate Rule-Access-When conditions L:IsProdAccess when there is no page to evaluate them against" appeared for the specific privileges. This was traced to a missed use case where the system falls back to the step page if the page for evaluating the 'when' condition is null, which did not account for scenarios where the step page can be null. To resolve this, a null check has been added which will fetch the primary page if the step page for the access 'when' condition is null.

Improved disconnected requestor cleanup for FieldService
Resolved in Pega Version 8.3.6
A large number of requestors from FieldService with the status as 'Disconnected' were accumulating and causing performance issues. This was traced to the requestors not getting passivated due to users not logging out and new requestors being created for the same users next time, and was caused by the value of the DSS Initialization/PersistRequestor being set as "OnTimeout". When the DSS prconfig/timeout/browser/default is not configured, the default browser requestor timeout is 60 minutes. In this scenario, requestors were not passivating as the requestor passivation timeout was set to the refresh token lifetime for mobile users, which was very large and overwrote the DSS value. This has been resolved by removing the code which set the passivation timeout to the OAuth2 refresh token lifetime.

Updated upgrade handling for migrating work objects
Resolved in Pega Version 8.3.6
After upgrading from Pega 6.2 to 8.3, the work migrated work objects were missing SLAs due to missed entries in the assignment tables (PC_ASSIGN_WORKLIST/ PC_ASSIGN_WORKBASKET) . The SLA was firing, but the processing failed due to the fact the runtime could not resolve a 'AddHistoryPage' library function. In this case, multiple upgrades of the application dating back to Pega 4 resulted in the runtime context containing older ruleset versions in higher ruleset versions, hiding the underlying Pega 8 version of the rule. For releases prior to Pega 7.3, Rule-Application was stored in pr4_rule and will be migrated to pr4_rule_application during upgrades. However, since Context Upgrade is run before Optimize Newly Exposed Columns, the pyDependsOnName won't always be populated. To resolve this, the system will filter based on the value in the blob rather than the exposed column so there will be a value regardless of the upgrade-from version.

Configuration added for extending queue processor timeout
Resolved in Pega Version 8.3.6
Alerts for queue processor (QP) items which took more than 15 minutes to run could result in the system marking the node as 'unhealthy'. In environments with Pega Health Check enabled, this would shut down the node gracefully. It was not possible to change this default as it was hardcoded. In order to support systems that may have custom processes that run beyond 15 minutes, a a new setting has been exposed that allows configuration of the interval after which a node with long-running queue processor is marked as unhealthy and is restarted. By default this remains 900000 milliseconds / 900 seconds / 15 minutes, but it may be adjusted up to 24 hours to avoid premature node shutdown. The stale thread detection mechanism will take that setting into account and use the provided value or default to 15 minutes if the value was not provided. In addition, the threshold's units in the UI have been changed from ms to seconds.

DSS DisableAutoComplete setting honored
Resolved in Pega Version 8.7.2
Setting DisableAutoComplete DSS was not working as expected. This was traced to the system not being able to read the DSS value due to timing related to database startup, and has been resolved by directing the system to read the setting in PREnvironment.java instead of from the prconfig.

Ruleset creation process updated to maintain thread scope
Resolved in Pega Version 8.7.2
On creating a ruleset, the system generated the error "There has been an issue. Please consult your system administrator." If browser cookies and site settings were cleared and the browser was relaunched before logging in and creating a ruleset, the issue did not occur. Investigation showed that the Application page was at the Requestor scope for some of the threads due to handling in the ruleset creation process that removed the Application page and recreated it in the default scope of the thread with the latest state. To resolve this, the process for deleting the Application page and recreating it on the Requestor page has been removed.

UI and code changes to support Client Assertion in Open ID Connect
Resolved in Pega Version 8.7.2
In order to support private_key_jwt, an enhancement has been added which will pass the “Client ID” and “Client assertion” (in the form of a signed JWT) as part of the authorization code grant flow for an IDP-initiated SSO. The Authorization Server will then authenticate Pega (the client) to verify the signature and payload of assertion by retrieving the public key via Pega’s JWKS endpoint.

at+jwt header type support added
Resolved in Pega Version 8.7.2
After upgrading from Pega 7 to Pega 8, using JWT validation in the REST service package with type "at+jwt" resulted in the JSON web token being rejected during signature verification with the error "header "typ" (type) "at+jwt" not allowed". Pega uses the third-party Nimbus jar to generate and verify JWT tokens, and this issue was traced to a difference in the versions of that jar: Pega 7.3 uses the nimbus-jose-jwt 5.1 version jar, while Pega 8.6+ uses the 8.20 jar version. Nimbus rejects at+jwt header types by default from the 8.0 jar version. To resolve this and improve backwards compatibility, at+jwt header type support has been added.
