Research direction
Start by reproducing the supplied verify(token, jwtSecret) call in the stated TypeScript, jsonwebtoken, and Next.js environment, then inspect the jsonwebtoken verify entry point involved in the error. Done means the reproduction no longer throws the invalid instanceof KeyObject TypeError, with the behavior covered by a regression test.
