This adds a second layout file (layout.jsx) in the same app directory where layout.tsx already exists. Next’s file-based routing expects exactly one layout per segment; having both extensions in the same folder results in a “duplicate layout” conflict or unpredictable file selection at build/dev time. Please remove the extra file or keep only one layout implementation.

This introduces page.jsx alongside the existing page.tsx in the same app directory. Next routes require a single page file per segment; multiple page.* files can trigger a duplicate page error or cause the wrong file to be used at runtime. Please remove one of the two so there’s a single source of truth.

- The mongoose.connect() call is not awaited, which means the connection may not be established when the User model is used. This could lead to runtime errors when trying to query or create users before the connection is ready. Either await this call or handle the connection promise appropriately.
