Javascript undefined error for JS Use APIs

[sjb1990]

Hi all,

I'm using AEM version 6.3.0.2 and created a component using sightly and JS use API. I keep getting this error. Its the same with other components as well.

org.apache.sling.engine.impl.SlingRequestProcessorImpl service: Uncaught SlingException

• org.apache.sling.scripting.sightly.SightlyException: No JavaScript engine was defined.

What could be the reason and how do we fix it? Thanks.

I've seen this before when the runmode is incorrect, you can check further on this by checking [1]

[1] /system/console/status-slingsettings

Please check if bundle "Apache Sling Scripting JavaScript Support" is in active state

Thanks. It was in resolved state. Once made active, it worked.
