This error indicates that a line in the input file being processed does not meet the expected length requirements defined in the mapping configuration.
  Cause:
  
  File Format Issues: The input file may not conform to the expected format, such as missing fields or having fewer characters than required.

  Check Input File: Review the input file to ensure that all lines meet the expected length requirements. Each line should have the correct number of fields and characters as defined in the mapping.
  Adjust Mapping Configuration: If the input file is correct but the mapping configuration is too strict, consider adjusting the mapping settings to accommodate the actual data structure.
  Data Validation: Implement data validation checks before processing the file to catch any issues early. This can include checking for empty fields or ensuring that the data conforms to expected formats.
  Error Handling: Enhance error handling in the AIF configuration to provide more informative error messages or to skip problematic lines while processing the rest of the file.
