I have a search.js file that reads a json file and retrieves information about some products, and then displays it in the page. I am trying to show a error message if no product is found when searching, and this part is almost working.

And the Python script: def clean_file(file_path): try: with open(file_path, 'r') as file: lines = file.readlines() cleaned_lines = [] for line in lines: # Diviser la ligne en champs, en supposant qu'ils sont séparés par '|' fields = line.strip().split('|') # Nettoyer chaque champ individuellement cleaned_fields = [field.rstrip('M').strip() for field in fields] # Reco
