I am working with the monorepo structure created after using create-next-turbo.

I am struggling to figure out how to get Chrome and/or Firefox to find the relevant sourcemaps. I think I have found where sourcemaps are being output, which is .rootappswebnode_modulesnextdistpages.

For some reason, Chrome/Firefox are unable to locate these sourcemaps automatically (I have verified the option to use sourcemaps are ‘ticked’ in settings).

I wonder if it’s a problem with my tsconfig.json given that there are effectively 3 tsconfigs at play. I know I need to clean this up, and will probably do that next!
