The function duplicates text extraction logic already present in the existing extract_text_from_pdf function. Consider reusing the existing function to avoid code duplication.

Inconsistent indentation: the function uses 7 spaces instead of the standard 4 spaces used elsewhere in the file.

The function returns different types (integer for success, string for errors). This inconsistent return type makes error handling difficult. Consider raising exceptions or returning a consistent data structure.

Suggested change
return "Error: PDF file not found."
except Exception as e:
return f"An error occurred: {e}"
raise FileNotFoundError(f"PDF file not found: {pdf_path}")
except Exception as e:
raise RuntimeError(f"An error occurred while processing the PDF: {e}")
