Nuxt 3 Generate - The message format compilation is not supported in this build

I am generating a static Nuxt 3 build but I am getting the following warning in my console

` WARN [intlify] The message format compilation is not supported in this build. Because message compiler isn't included. You need to pre-compilation all message format. So translate function return 'message.header'.`

I am using adding "@intlify/nuxt3" to nuxt modules with the intlify object and some messages.

I am rendering the translations as follows: `{{ $t("mainLayout.header") }}`

Any ideas what is causing this?
