Simple way to fixed it you need edit .env or .env.local file:

NEXT_PUBLIC_SANITY_PROJECT_ID=
NEXT_PUBLIC_SANITY_DATASET=production
NEXT_PUBLIC_SANITY_API_VERSION=
SANITY_STUDIO_PROJECT_ID=
SANITY_STUDIO_DATASET=production

need to duplicate it. with NEXT and without NEXT

• run again sanity deploy;
