Statistical Analysis [metadata table] 500-Internal Server Error

Hi, I have been trying to use statistical analysis metadata table but keep getting an internal server error after uploading my data. I get to the step shown in the photo and click proceed.

Once I have clicked on proceed, I get the following error:

HTTP Status 500 - Internal Server Error

type Exception report
messageInternal Server Error
descriptionThe server encountered an internal error that prevented it from fulfilling this request.
exception javax.servlet.ServletException: Cannot invoke “java.util.List.get(int)” because “this.metaDataBean” is null

root cause java.lang.NullPointerException: Cannot invoke “java.util.List.get(int)” because “this.metaDataBean” is null

note The full stack traces of the exception and its root causes are available in the Payara Server 5.2022.5 #badassfish logs.

What am I doing wrong? I am using the same files my PI used and they worked when she showed me how to do this process.
