GetProperties with the ‘Automatically Updates Values’ option does not properly handle reconnections after a user session times out in ThingWorx Mashup

Modified: 14-Jan-2026   


Applies To

  • ThingWorx Platform 9.3

Description

  • GetProperties with the Automatically Updates Values option does not properly handle reconnections after a user session times out or a platform restart
  • SecurityLog is flooded with "Rejecting NonceKey [<Key ID>] since it was not found in cache" errors
  • After reconnection, the mashup is calling every second (or even more frequently) :
    • /Thingworx/Resources/EntityServices/Services/GetClientNonce, which return an empty response
    • /Thingworx/WS with an obsolete nonce / appkey
    • SecurityLog.log repeatedly report below warning messages:
    • [L: WARN] [O: S.c.t.s.m.ApplicationKeyManager] [I: ] [U: ???] [S: ] [P: ] [T: https-jsse-nio-443-exec-129] *** ApplicationKey not found ***
[L: ERROR] [O: S.c.t.s.m.NonceKeyManager] [I: ] [U: ???] [S: ] [P: ] [T: https-jsse-nio-443-exec-129] Rejecting NonceKey [<Key ID>] since it was not found in cache
  • The behavior varies depending on the browser vendor and whether SSO is used:
    • Chrome + Basic Auth (Authentication Dialog does not show on MacOS)
      • GetClientNonce is invoked every seconds and a new Basic Auth dialog pops up until credentials are provided
    • Firefox + Basic Auth
      • GetClientNonce is invoked once, the Basic Auth dialog pops up, and the Mashup is suspended until credentials are provided
    • All browser + SSO:
