Final loader didn't return buffer or string

[artnova-david]

Reporting a bug?

After upgrading yaml-loader from v0.6.0 to v0.8.0 I got this build error on .yml files: "Final loader (./node_modules/@intlify/vue-i18n-loader/lib/index.js) didn't return a Buffer or String"

Expected behavior

Build with no errors :)

Thank you for your reporting!

hmm, 🤔 we need yaml-style i18n locale messages that are not processed by vue-i18n need to be ignored and pipelined with the rest of the loader pipeline.
