An error occurred while processing the template.
The following has evaluated to null or missing:
==> restClient.get("/headless-delivery/v1.0/sites/${groupId}/structured-contents/by-key/${journalArticleId}?nestedFields=embeddedTaxonomyCategory").taxonomyCategoryBriefs [in template "17855804202317#32484267#LEARN-ARTICLE" at line 5, column 34]
----
Tip: It's the step after the last dot that caused this error, not those before it.
----
Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
