Escaping rules change based on import file?

[viveleroi]

I have a string in my .env file with a $ character: FOO="123$"

I'm using this with vitest and playwright. In vitest, I get an error about escaping a character in my env file that has a $ in it:

dotenv-expand failed to expand env vars. Maybe you need to escape $?

Escaping said character solves the problem.

Yet when I run playwright, the escaping is not needed and actually is seen as part of the string.

console.log(FOO) // prints 123\$

EDIT: For now we have fixed this by specifically calling dotenv-expand in the playwright file: dotenvExpand.expand(dotenv.config({ override: true }))
