Getting Error IC0302 when I export static. (nextjs + rust)

Developing IC application with nextjs and Rust environment. It works with development mode by next dev command. but when I generate statics by next build and next export. It does not work. In console I see below error. I tried to use sdk version 7.0.1 and 7.0.2. both was same issue. I may have issue in my code.
