Error calling index: index of untyped nil

#1

Hello,

I have an error, but it’s rendered correctly.
In my partial it gets the data, and it renders in the frontend.

`{{ \$data := index (index \$.Site.Data \$.Site.Language.Lang).usp "large" }}`

but i have this error
`at <index (index \$.Site....>: error calling index: index of untyped nil`

I have a more simpler approach now, but it will be nice to fix the above issue
`{{ \$data := (index \$.Site.Data \$.Site.Language.Lang).usp.large }}`

All the best,
Erol
