I am getting an error as below when i am trying to open a page

Error during include of component '/apps/lifescience/components/page/basePage'

Error Message:

org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.sightly.SightlyException: org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.sightly.SightlyException: data-sly-call: expression evaluates to null.

The base page HTML has:-

   <div data-sly-call="${clientLib.js @ categories=['ABC']}" data-sly-unwrap></div>

   <div data-sly-test="${inheritedPageProperties.bodyJS}" data-sly-unwrap>
       ${inheritedPageProperties.bodyJS @ context='styleToken'}
   </div>
</body>

The situation came when i have upgraded from 6.0SP3 to 6.2 SP1 . Please help . Thanks in advance .

Hi,

Not quite sure, but you might want to try few of the below options and see if it helps.

1]data-sly-call="${clientLib.js @ categories='customvalue'}". Use this and see, reason being I see some [] brackets in your case.

2] Validate if the corresponding 'categories' are present under etc nodes, as there are chances that it might have got missed.

3] Also, have seen categories="htlajax" being used in 6.2 Not quite sure if using that name helps, but you might try looking for more info on this.

Hi,

"data-sly-call: expression evaluates to null." is something that I see in error stack trace.

1] Looks there there is some issue in statements where this is used, where the custom client lib related things are getting called. You might want to cross-verify this once.

2] This to me looks like a custom-code issue/mistake than upgrade issue.

You can await response from other community members as well on this.

Do you ahve custom components in your AEM instance - or are you using all OOTB components?

We do have custom components. Actually the entire project was working on 6.0 when i deployed the same project in 6.2 initially bundle was on resolved state . I have changed dependency then the bundle got active . I tried opening a page its throwing data-sly-call evaluates to null . The code base is running good in 6.0 . The body.html of the page goes below .

   <div data-sly-call="${clientLib.js @ categories=['lifescience.site']}" data-sly-unwrap></div>

   <div data-sly-test="${inheritedPageProperties.bodyJS}" data-sly-unwrap>
       ${inheritedPageProperties.bodyJS @ context='styleToken'}
   </div>
</body>
