t or Split is undefined 8.17.4 but nothing when rollback

[GoatFreezy]

Hello,
We have our CI which updated vuei18n to the lastest version (8.17.4) at our last deployement.
unfortunatly this cause our whole website to crash with 2 different errors :
"t is undefined"
"TypeError: Cannot read property 'split' of undefined"

We stuggled on detecting it because with the browser cache the website was correctly loading, so all developpers didnt had the error.

I was able to make our website functionnal after rolling back to the version we used to have : 8.12.4.

Our major probleme is that with the browser cache in local we dont have any error, it only happends on servers.

Same thing here. It happens when vue-i18n is set to a locale that is not listed in browser locales. Reverting to v8.16.0 which was the last one working for me.

Happens here and fails with TypeError: Cannot read property 'split' of undefined. Sentry shows that the error is thrown on render. I attach the respective (unfortunately minified) error snippet below.

{snip} U.prototype._appendLocaleToChain=function(t,e,n){var i,r=e.split("-");do{var a=r.join("-");i=this._appendItemToChain(t,a,n),r.splice(-1,1)}w {snip}

Hope it helps a bit.
