Ah, unfortunately it is what it says, you can't use TH in this scenario.
There is a workaround at
https://www.haskell.org/ghc/docs/7.8.3/html/users_guide/template-haskell.html,
section 7.16.4, maybe it will work for you.

If it's possible to temporarily disable the TH in question (stick
undefined in place) then that might be easier although I don't expect
that's easily achievable, I think you mentioned ~800 modules.
