OOTB Navigation component model class error

[#1]

Hi All,

I am using OOTB navigation component on my local AEM6.4 instance and its working fine as per the behavior but when I am using the same component on my client AEM6.4 instance( DEV and all instances) , I am getting model class missing error:

As compared with my client machine AEM6.4 and my local machine AEM6.4, I am using SP6.4.2 and acs-aem-commons-content-3.16.1-SNAPSHOT.zip on my local machine but both the package were not available on client machine. I have tired to install both the package also even after that I am getting the same error.

Please suggest which supporting package is missing here for navigation component.

thanks

Try and recompile your libraries [1], if not perhaps rebuild your bundle.

Just adding to what Yanira mentioned you can use Diff tools to verify if there is any config changes between the working and non-working instances: AEM Tools for environment comparison

Please check if core component bundle is active state or not? There could be possibility you have multiple version core components jar.

Compare runmode of local vs DEV/other env.
