Additionally, there is console error that occurs when the form loads that reads: Uncaught TypeError: Cannot read property 'bind' of undefined Also the offensive code (traced in the console) has the following format return unreachableFunctionFoo.bind(null)} Release All Environment Madrid Cause This may be caused by a custom code invoking an unreachable function due to domain separation. A more concrete example, would be a domain separated UI Action's onClick field trying to invoke a function that is not defined in the UI Action's domain, or leaving blank the script field of the UI Action. Resolution This can be solved by defining the onClick function on the script field of the UI Action.
