The required EC Entities configurations are not provided in Manage Business Configuration.

• Replicate the issue and check the error in console using the Developer Tool.
• Similar error as following will appear- The following problem occurred: HTTP request failed500,Internal Server Error,{
  "error" : {
  "code" : "ServerErrorException", "message" : {
  "lang" : "en-US", "value" : "Invalid property names: PerPersonal/firstNameAlt1. Please check the property name in Admin Center > OData API Data Dictionary or entity metadata. Ensure there were no data model changes that removed this field, and please execute a refresh metadata to ensure the cache is not corrupted."
  }
  }
  }
• The Property name would be missing for the respective entity in OData API Data Dictionary. In the above case firstNameAlt1 was missing for PerPersonal entity.
• The respective field needs to be enabled in Manage Business Configuration page(No need to make mandatory). The first-name-alt1 field under the personalInfo HRIS element was not enabled which caused the above error.
• Enable any such missing field under the respective HRIS Entity mentioned in the error.
• For above error first-name-alt1 had to be enabled to resolve the issue.
