Describe the Bug

Actually, I’m using Monorepo with turborepo and one of the apps is a next.js with middleware, so when trying to deploy at vercel, I received this error:

Error: Mapping apps/web/middleware not found. Maybe you provided a wrong middlewarePath? Available paths: middleware

At first, I understood that it was a platform error, however, after contacting the platform, I received a message saying that they do not solve problems related to the code.the

Expected Behavior

Just deploy correctly

well, for some reason after I changed the FRAMEWORK PRESET at Build & Development Settings the deploy just worked! I keep this issue open but feel free to close it if you feel the need as it is now working for me.
