Can't jump to next channel when bot does not have permission to send message discord.py

Question

So, I wrote some code, that sends a message to each channel in a server;

server_id = 974656708672925260
            message = "test"
            thread = 20
            channels = client.get_guild(server_id).text_channels
            channel_count = len(channels)
            for i in range(thread):
                for i in range(channel_count):
                    channel = client.get_channel(channels[i].id)
                    await channel.send(message)

And when the bot does not have permission to send messages in the server, i get en error. Is it possible to just ignore that channel, and jump to the next one?
