This error can arise in various contexts, such as during data uploads, interface processing, or when working with custom developments.
  Causes:

  Data Type Issues: There may be issues with data types, such as trying to insert a string into a numeric field or vice versa.
  
  
  Custom Code Issues: If there is custom code involved in processing the extension structure, there may be bugs or logical errors in that code.
