Replacing google slides images using slides api

I have the following scripts to update the images in google slides, it works fine but sometimes it gives me 400 error, service account has a write permission to the drive/images and the presentation

image_mappings = {"id_in_presenation": "name_of_the_image","id_in_presenation1": "name_of_the_image1",}# listing .png files def get_png_files(drive_folder_id, drive_service):    query = f"'{drive_folder_id}' in parents and mimeType='image/png'"    results = drive_service.files().list(q=query, supportsAllDrives=True, fields="files(id, name, webViewLink, webContentLink)").execute()    drive_png_files = results.get('files', [])    print('drive_png_files', drive_png_files)    return drive_png_files`# updating images in slidesdef update_images_in_slides(drive_png_files, slides_service, presentation_id):"""    Updates images in a Google Slides presentation.
