2023-05-26 13:32:51.826 ERROR [http-nio-8080-exec-5][runtime:59] Error executing FreeMarker template
freemarker.core.InvalidReferenceException: The following has evaluated to null or missing:
==> sign_in_url [in template "my-liferay-theme_SERVLET_CONTEXT_/templates/portal_normal.ftl" at line 40, column 89]
----
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)??
