When building throws this warning (node:19188) [DEP0148] DeprecationWarning: Use of deprecated folder mapping "./" in the "exports" field module resolution of the package at xxxxx\node_modules\tslib\package.json. Update this package.json to use a subpath pattern like "./".

Thanks @Oliver-Piorun it worked, only getting a strange message

Hi! Seems like this issue/warning is already known: https://github.com/microsoft/tslib/issues/134 Does it affect the build of your sapper app?

Greetings!

[go-aegian]

Hi Oliver, thanks for your reply. No it does not affect build/run at all.
