• What is the cause and solution for SAP error message SRF_AUTHORING539 - Invalid JSON schema. Array property &1 does not contain 'items' keyword. ?

  The SAP error message SRF_AUTHORING539 indicates that there is an issue with the JSON schema being used in your SAP application. Specifically, the error states that an array property in the schema does not contain the required 'items' keyword. This is a common issue when defining JSON schemas, as the 'items' keyword is necessary to specify the type of items that the array can contain.
  Cause:
  The error occurs when:
  
  An array property in your JSON schema is defined without the 'items' keyword.
  The 'items' keyword is essential because it defines the schema for the items within the array. Without it, the schema is incomplete and cannot be validated.
  
  Solution:
  To resolve this error, you need to modify your JSON schema to include the 'items' keyword for any array properties. Here’s how you can do that:
  
  
  Locate the JSON Schema: Identify the JSON schema file that is causing the error.
  
  
  Edit the Schema: Find the array property that is missing the 'items' keyword. It should look something like this:
  {
      "type": "array",
      "properties": {
          "myArray": {
              "type": "array"  // This is missing 'items'
          }
      }
  }
  
  
  Add the 'items' Keyword: Modify the schema to include the 'items' keyword, specifying the type of items the array will contain. For example:
  {
      "type": "array",
      "properties": {
          "myArray": {
              "type": "array",
              "items": {
                  "type": "string"  // Specify the type of items in the array
              }
          }
      }
  }
  
  
  Validate the Schema: After making the changes, validate the JSON schema to ensure that it is correctly defined and does not contain any other errors.
  
  
  Test the Application: Once the schema is corrected, test your application to ensure that the error is resolved.
