Answer 1

It’s because message is not a valid parameter for interactionCreate.
As the discord.js docs implies, you can only pass in interaction in an interactionCreate event.
This should work for your code:
content: `🏓Latency is ${Date.now() - interaction.createdTimestamp}ms.`,

Answer 2

interactionCreate event cannot have message parameter...
client.on('interactionCreate', async interaction => {
// your code here
})
