AttributeError: 'Chat' object has no attribute 'access_hash'

[siddAhmed]

I have done everything correctly (i guess) but every time it throws this error.
Any clue what's wrong?

The console throws this error :

  File "forwardgram.py", line 49, in <module>
    start(config)
  File "forwardgram.py", line 24, in start
    output_channel_entities.append(InputChannel(d.entity.id, d.entity.access_hash))
AttributeError: 'Chat' object has no attribute 'access_hash'

Hi, Can you find any solution about this error?

[ekkutlu]

Any solution??

Juat update your python version and make sure you have the chats and proper permissions accessing them.

I also ran into this problem. It seemed to be caused mostly when trying to forward from a group chat instead of an actual channel even though the distinction is not always apparent in Telegram. (I think) only channels have an access_hash, hence the error (at least that was the case for me).

I found initially running something like:

for d in client.iter_dialogs():
        print(d.name + ": " + str(d.entity.id)

outputs the shorter id codes for all channels and chats on your Telegram account which can then be used to build your input and output channel entity lists using the simpler and less error-prone:
output_channel_entities.append(12345678)
where 12345678 was the short id codes from above.

Optionally - If you change any code in and around the event handler and hit further issues sending to a chat vs channel, then inside the handler you can check:

if isinstance(event.to_id, PeerChannel): #check if channel or chat (they may need to be handled differently)
    print("do something with channel")
elif isinstance(event.to_id, PeerChat):
    print("do something with chat")
else:
    print("if you reach here, give up and go grab beer!")

I'm still learning Python so I'm sure there will be better ways but this is what worked for me when trying to handle both Chats and Channels.

I've used @Bee53Apps 's method and succeeded, just need to mention you need to create a bot and make the bot the admin of the target channel in order to forward something there. Also it's wired that it is constantly showing:

2021-05-15 02:22:17,241 - root - INFO - Listening on 1 channels. Forwarding messages to 2 channels

And the forwarded msg repeated itself for twice? Anyone has some idea? Thanks in advance.
