Bot Randomly Crashes

[Tnology]

Bug Report

The bot will sometimes crash at random with an "Uncaught DiscordAPIError" as seen below:

error: Uncaught DiscordAPIError:

Expected Behavior

The expected behavior is the bot not crashing at random.

How to Reproduce

I can't seem to find a trigger for this error, it just seems to happen at random while the bot is running. However, I have noticed that there is no "main.ts" within the error - only Harmony's bucket.ts and memberRoles.ts and similar. The crash isn't immediate, it takes some time with the bot running for the bot to crash.

Additional Context

I posted a screenshot of this error in Harmony's official Discord server, and one of the developers replied with "huh" - I said "I suppose this is an issue with Harmony?" to which they said "probably.."
