channels.getMessages throws Error: Invalid vector object "Vector<int>" about airgram HOT 7 CLOSED

Please check out parameters of the chanels.getMessages method. You should pass list of message id that you need to get.

from airgram.

I guess you need method messages.getHistory.

Sorry for the late message. Yes I needed to use the messages.getHistory It was not intuitive to name channel.getMessages. But I have another doubt. How can I download a image or any media? I dont want to open another issue/question for this.

I tried using

upload.getFile({
  location: {
    _: 'inputDocumentFileLocation',
    id: message.media.id,
    access_hash: message.media.access_hash
    version: ?
  }
})

But it throws RpcError: CODE#400 LIMIT_INVALID

I don't understand why getting one image needs limit and offset parameters. Also what number should be fed into version?

from airgram.

Try to add additional options:

client.upload.getFile({
      location: { ... },
      offset: 0,
      limit: 1024 * 1024
}, {
      isFileTransfer: true,
      createClient: true
})

I don't understand why getting one image needs limit and offset parameters.

This parameters described in schema.tl. Airgram does not change original Telegram API.

Also what number should be fed into version?

Where did you take location value?

Hello I've figured it. By the way this is a very useful library and I appreciate your effort. I didn't mean any disrespect or if I had been rude, I apologise. Its just a little frustrating with their API docs.

The answer is not to use id and access_hash instead use the sizes object in media.photo and get the desired size using the secret, volume_id and local_id. I hope this issue is useful for someone who is in the same boat as me.
