 I&amp;#39;m fairly new to Appian. 
 While tailing the tomcat log, I see when the ObjectSynchronizer runs, I get the following: 
 ... WARN com.appiancorp.common.ObjectSynchronizer - 1 services were missing users. ...

And if so can you give some more information about where you&amp;#39;re encountering the error? I mention this because the tomcat log is very noisy - it&amp;#39;s a good place to go if you already know there is a problem, but it&amp;#39;s not a great place to determine if there is a problem or not.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Unique Constraint During Synchronization</title><link>https://community.appian.com/thread/136214?ContentTypeID=1</link><pubDate>Fri, 31 May 2024 16:07:45 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:1ce72daf-84ad-41ab-9713-dbf936799907</guid><dc:creator>Stefan Helzle</dc:creator><description>&lt;p&gt;Not really, but you will probably not get much help from Appian for an unsupported version.&lt;/p&gt;
&lt;p&gt;And yes, I know this is probably not the answer you were hoping for.&lt;/p&gt;
&lt;p&gt;Is this a self-hosted environment? If yes, you could try to check the DB logs for this error. If this is in cloud, get it updated.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Unique Constraint During Synchronization</title><link>https://community.appian.com/thread/136212?ContentTypeID=1</link><pubDate>Fri, 31 May 2024 16:02:59 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:67cf1a66-addb-45e7-97a8-515228b256fa</guid><dc:creator>raymond_k</dc:creator><description>&lt;p&gt;Is upgrading going to answer any of my questions???&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Unique Constraint During Synchronization</title><link>https://community.appian.com/thread/136209?ContentTypeID=1</link><pubDate>Fri, 31 May 2024 15:34:16 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:24176473-674d-4626-928c-8e8ef73e44bd</guid><dc:creator>Stefan Helzle</dc:creator><description>&lt;p&gt;21.3 ?&lt;/p&gt;
&lt;p&gt;I think the best you can do is to upgrade to a supported version.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
