I'm having some trouble with my discord bot and I could really use some help

Currently my bot executes this piece of code, and it works perfectly most of the time:

if (message.member.roles.cache.has('917521104908742736')) //muted role
{
        return message.delete();
}

However, from time to time, the bot crashes randomly, giving out the following error:

TypeError: Cannot read property 'roles' of null

I don't know what to do anymore, and even worse is that the program crashes randomly, so I don't know what exactly causes the error. Could you help me, please?

The message object doesn't seem to have the member property (maybe because the message has been sent in DMs), try to add the interogation mark for Optional chaining :

if(message.member?.roles.cache.has('917521104908742736')) {
  return message.delete();
}

The bot simply receives DMs. Check if it's a DM, and return early if it is:

if (!message.guild) return;
