Known Issues and Workarounds
|
---|
Platform
|
Due to possible security vulnerabilities, a minimum version of Apache Tomcat 8.5.42 or 9.0.21 is required. It is strongly recommended that you upgrade Apache Tomcat to these versions to mitigate known security issues with older versions of Apache Tomcat.
|
If you are upgrading to 8.2.14, it is recommended to set the runAsUser field for the AuditArchiveCleanupNotificationScheduler, AuditArchiveScheduler, and AuditArchiveCleanupScheduler system objects to avoid error messages in the Application log upon platform startup. If the runAsUser is left blank, the schedulers will be inactive. This issue will be fixed in a future release.

• Fixed an issue that was causing the following licensing error: Unable to retrieve license from FNO server because Connect to fnoauth.ptc.com:443 ... failed: Connection timed out. To fix this issue, new optional parameters were added to the platform-settings.json file in the LicensingConnectionSettings section to allow a proxy server to be configured with ThingWorx.
