Description
Hello, I encountered a type-length limit error when using axum in my project. The error occurs when I execute cargo run. Here are the details of my setup and the error message:

It is confusing because the GitHub workflow of my project showed that the build passed on June 28th, so I'm not sure if it's caused by the nightly version of the compiler.
