Hi everyone!

I'm currently starting using Appian and I'm in "Create an Application: First Steps for Appian Analysts".. 

But for some reason, when I try to use Appian Composer, it shows an error and I can't move on.


and also if I want to select a predefined app, it shows the following message

Código HTTP: 500 APNX-1-4198-000 Error al evaluar la expresión de UI Error de evaluación de expresión [evaluation ID = H0RT7] : [valid:false,syntaxError:false,value:Error de evaluación de expresión: Se produjo un error al ejecutar una operación de guardar: java.lang.RuntimeException: AI Platform API error: [AIP_1_000] message="Error calling AI Platform messagesCall" (Error Code: AIP_1_000)]


Has anyone else had this problem? Am I doing something wrong maybe?

I've already sent a e-mail as well

Cheers!!
