Cannot read properties of undefined (reading 'startsWith') in Commands.js of tmi.js

[D3FAU4T]

Actual behaviour:
I'm getting this same error occasionally and it is crashing my bot. I'm pretty sure it's an error in the tmi.js lib and not in my bot. Please check this issue.

Expected behaviour:
I should not get any error from tmi.js while my bot is running.

Error log:

/home/runner/username/node_modules/tmi.js/lib/commands.js:342
        if((message.startsWith('.') && !message.startsWith('..')) || message.startsWith('/') || message.startsWith('\\')) {
                    ^

Check to make sure you're not calling client.say without a message argument. The arguments are channel then message. If message is not a string you will get an error.

client.say('alca', 'Thanks for lurking!')
