  The SAP error message /UI5/JSON_SCHEMA_CHK003 indicates a property type error in a JSON schema validation process. This error typically occurs when the data type of a property in a JSON object does not match the expected type defined in the schema. The message provides specific details about the property in question, including:
  
  Prop: The name of the property that is causing the error.
  Exp: The expected data type for that property.
  Act: The actual data type that was found in the JSON object.
  
  Cause
  The error is caused by a mismatch between the expected and actual data types of a property in a JSON object. For example, if the schema expects a property to be of type string, but the actual value is a number, this error will be triggered.
  Solution
  To resolve this error, you should:
  
  
  Check the JSON Object: Review the JSON object that is being validated. Identify the property mentioned in the error message and check its value.
  
  
  Verify the Schema: Look at the JSON schema that defines the expected types for the properties. Ensure that the data types in your JSON object match those defined in the schema.
  
  
  Correct the Data Type: If the actual data type does not match the expected type, modify the JSON object to ensure that the property has the correct type. For example:
  
  If the schema expects a string, ensure that the value is enclosed in quotes (e.g., "value").
  If the schema expects a number, ensure that the value is a valid number without quotes (e.g., 123).
  
  
  
  Test Again: After making the necessary corrections, re-run the validation to ensure that the error has been resolved.
