Hi,
We are getting some warning messages in logs.
28.07.2020 01:15:11.225 *WARN* [10.43.32.87 [1595898911218] GET /content/diagnostics/be/en/products/product-category/clinical-chemistry-and-immunochemistry.html HTTP/1.1] org.apache.sling.scripting.sightly.js.impl.jsapi.ProxyAsyncScriptableFactory Script /libs/wcm/foundation/components/page/head.js uses the deprecated asynchronous API provided by the 'granite' namespace. Please refactor the script to use the synchronous API provided by the org.apache.sling.scripting.javascript bundle.
Could you please let us know how to resolve this.
we have been upgraded from aem 6.2 to 6.4
is this upgrade issue or we need to update head.js file or any API.
