Issue

  • While trying to expand the accordion sections of "Scopes" for the OAuth2 Administration tab in Control Panel, customers may face the inability to do so as well as the below error in the browser's console:
    Uncaught TypeError: Cannot read property 'querySelectorAll' of null 
    at Collapse._getParent
    This will happen even when Liferay DXP 7.1 is patched to Fix Pack 13+, therefore having the solution for https://issues.liferay.com/browse/LPS-94202

Environment

  • Liferay DXP 7.1 Fix Pack 13+
  • Liferay Plugin for OAuth 2.0 version 1.0.0

Resolution

  • 1) Go to Control Panel - Configuration - Gogo Shell
    2) Type command lb oauth and click on Execute:

    Is your Liferay Plugin for OAuth 2.0 (API and Impl) minor than 1.1.1?

    If it is, please proceed with the below steps:

    3) Go to Liferay Plugin for OAuth 2.0 page on the Liferay Marketplace
    4) On top-right, click on the "Free" button
    5) Fill in the required info, if you agree on the terms
    6) Click on "See Purchased"
    7) Click on "Past Versions"
    8) Click on the "App" button for Version 1.1.1 if you are running a 7.1 version below Fix Pack 17, otherwise, select Version 1.1.2 
    9) Deploy the .lpkg file to the affected Liferay instance
    10) Wait for successful deployment and the message asking to restart the server
    11) Stop the server
    12) Empty the content of the following folders:
    -- Liferay/osgi/state
    -- Liferay/work
    -- Tomcat/work and Tomcat/temp
    13) Clear the browser's cache
    14) Restart the server
    15) Upon successful startup, the issue should be resolved
