"tasks" is available to turbo 2.x. Therefore, the error is occurring because "tasks" cannot be read. As a solution, change "tasks" to "pipeline," which can be read by version 1, and then run npx @turbo/codemod update, which will automatically update it.

I believe this is fixed by https://github.com/vercel/turborepo/pull/10295. Please let me know if not and I'll reopen.
