g_form.setLabel does not work on platform for catalog client scriptIssue The g_form.setLabel method is not listed in the GlideForm API documentation which means it is not supported. However, since it is a supported method for mobile as stated in the Mobile GlideForm API documentation it will also work with Service Portal. As an allernative to the setLabel method in the GlideForm API is the setLabelOf method. However, this isn't supported in Service Portal.
