This error can occur in various contexts, such as when working with SAP UI5 applications or when handling JSON data in ABAP programs.
  Causes:
  
  Invalid Data Types: The data being serialized may contain unsupported or invalid data types that cannot be converted to JSON format.
  Circular References: If the data structure has circular references, the serialization process may fail.
  Null or Undefined Values: Attempting to serialize null or undefined values can lead to serialization errors.

  Encoding Issues: Special characters or incorrect encoding in the data can cause serialization to fail.
  
  Solutions:
  
  Check Data Types: Ensure that all data types being serialized are supported by JSON. Convert any unsupported types to a compatible format.
  Remove Circular References: If your data structure has circular references, refactor it to eliminate these references before serialization.
  Handle Null Values: Ensure that you are not trying to serialize null or undefined values. You can either filter them out or provide default values.
  Limit Data Size: If the data is too large, consider breaking it into smaller chunks or reducing the amount of data being serialized.
  Validate Encoding: Check for special characters in your data and ensure that they are properly encoded. Use functions to escape characters if necessary.
  
  Related Information:
  
  Debugging: Use debugging tools in SAP to trace the data being serialized and identify the exact point of failure.
