Confirmed updating Typescript from v3.9.x to ^4.0 resolves this issue
npm i -D typescript@^4.0I would suggest updating the package dependencies to suit
Lowercase<T>was introduced with TypeScript 4.1, so using any version newer then that should fix this problem.I confirm upgrading typescript to 4.2.4 works. Closing the issue. Thanks all.
Just ran into the same issue on our CI after upgrading to 8.0.0. Rolled back to 7.1.0, and don’t have the issue anymore.
Anyone managed to fix that issue?
I just created a definition file that I added to my tsconfig.json including:
And that fixed it for now. Not ideal though.
Had the same issue. I upgraded the typescript from 3.9 to 4.1 and it solved the problem. Thanks to @dbryar
