Telegram Bot with aiogram: File Identifier Issues

Other Questions Telegram bot

I’m encountering file identifier errors in my Telegram bot using aiogram. How can I resolve these problems? Below is a sample:

from aiogram import Bot, Dispatcher, executor, types

bot_obj = Bot(token='REPLACE_WITH_TOKEN')
disp = Dispatcher(bot_obj)

@disp.message_handler(commands=['pic'])
async def send_image(msg: types.Message):
    try:
        await bot_obj.send_photo(chat_id=msg.chat.id, photo='NEW_IMAGE_ID')
    except Exception as e:
        print('Send photo error:', e)

if __name__ == '__main__':
    executor.start_polling(disp)

hey try grabbing the actual file id from a sent photo instead of a new one. u might avoid errors by caching that id and ensuring the image is properly uploded. a small delay might be all it takes…

I encountered similar problems before and found that verifying the file upload process and the corresponding file identifier is crucial. Instead of manually entering new image IDs, I recommend sending a test photo to your own bot and logging the file_id from that response. This ensures that you have the correct identifier recognized by Telegram. It is also advisable to check your aiogram version since updates may resolve caching issues related to file identifiers. In my experience, this method provided a reliable solution.

During my troubleshooting phase, I encountered similar file identifier issues, and eventually I resolved it by updating both my aiogram library and my bot’s API version. I also discovered that using images that I uploaded during testing and then logging their file IDs significantly helped track down the error. Ensuring consistency in the way the file IDs were stored and used was critical in my case. The problem often stemmed from using stale identifiers from earlier uploads. A thorough check of library versions and storing the correct file IDs after a test upload made the difference.

hey, i solved it by sending the actual image to get the id realtime. sometimes older id’s become invalid. also, check if your aiogram version needs an updtae since it sometimes fixes caching issues.

My experience with file identifier issues in aiogram taught me that these identifiers can become invalid if not handled correctly. I resolved similar problems by ensuring I always retrieved a fresh file identifier by sending a sample image and using the response from Telegram, rather than relying on a stored value. I found that using logging to capture the file details right after an image upload is critical. This way, you can confirm that you are using the most current file identifier and avoid potential mismatches due to caching or outdated references.
