format yyyy-MM-dd don't work like as before

[Quineone]

version: "@nuxtjs/date-fns": "^1.5.0"

For now only uppercase fromat string can work, like YYYY-MM-DD

{{ $dateFns.format(new Date('2021-05-01'), 'yyyy-MM-dd') }}  // output `yyyy-05-za`

{{ $dateFns.format(new Date('2021-05-01'), 'YYYY-MM-DD') }}  // output `2021-05-01`

We are having the same issue. Seems like it's not backward compatible.

I face this issue because I install @nuxtjs/apollo before @nuxtjs/date-fns.

@nuxtjs/apollo require date-fns version ^1.27.2
@nuxtjs/date-fns require date-fns version ^2.19.0.
I look at the package-lock.json it makes date-fns version ^1.27.2 is the main version of the app. when you import date-fns on the app it will use this version.

I solved this issue by

1. remove package-lock.json
2. run npm install to recreate package-lock.json again to make version ^2.19.0 be the main version.
