The entity name must immediately follow the '&' in the entity referenceIssue This issue occurs when a web application processes data containing special characters like the ampersand (&) but does not properly encode it before displaying it in an HTML interface. When an application processes and displays data, it might include the ampersand (&) character.In HTML, & is a reserved character used to start an entity reference (ex., & represents &).If the application fails to encode & properly (ex., as &), the HTML parser expects a valid entity name to follow it.SymptomsSome applications fail and the error displayed is: The entity name must immediately follow the (&) in the entity reference. ReleaseAll ReleasesCauseThe web applications internally work with the data. On certain conditions, the data could interfere with the interface rendering the data itself. On this case, the data that contains and (&) that is not translated to the equivalent web escaped code, and it could breaks the user interface HTML. The application is working with raw data containing & without translating it to &.ResolutionMake sure the following system properties are set to true in your instance: glide.ui.escape_all_scriptglide.ui.escape_textRelated LinksDocumentation: Escape XML (instance security hardening) Escape jelly script [Updated in Security Center 1.3 and 1.5] Knowledge: Troubleshooting error "Entity name must immediately follow <character> in the entity reference" Community: The entity name must immediately follow the '&' in the entity reference
