JDA: Unknown Channel error by sending messages to deleted channels with no way to check if deleted or not beforehand

General Troubleshooting

• I have checked for similar issues.
• I have updated to the latest JDA version.
• I have checked the branches or the maintainers’ PRs for upcoming bug fixes.

Bug Report

When queueing a message using TextChannel.sendMessage("").queue(); I get an Unknown Channel Error thrown even though i checked for write permissions to the channel. Meaning I get True returned from TextChannel.hasPermission(…); when applied on a deleted text channel.

Is there maybe a way to check if a text channel has been deleted or not? I couldn’t find any way myself.

Expected Behavior

I store text channel id’s in a database to post messages at certain intervals. Before sending a message I check for write permissions in order to make sure my bot is able to post in the text channel.

Code Example or Reproduction Steps

String channelID = "abcdefg" //Id of a previously deleted channel here JDA.getTextChannelById(channelID).sendMessage("").queue();

Code for JDABuilder or DefaultShardManagerBuilder Used

DefaultShardManagerBuilder builder = new DefaultShardManagerBuilder(); String token = "XXXXX"; builder.setShardsTotal(10); builder.setToken(token); builder.addEventListeners(new Main()); shardManager = builder.build();
