Problems with rust-analyzer on vscode

I'm trying to make a new project using esp-idf with rust, and I can setup and build correctly on the terminal. The only problem is that the rust analyzer extension does not work correctly, which makes it hard to develop.

For example, some stuff works, but a lot doesn't work and keep as {unknown}

The repository of the project is https://github.com/metehus/esp-rs-idf-poc

The output of the extension is the following:

2024-08-29T23:24:45.154086Z ERROR FetchBuildDataError:
The following warnings were emitted during compilation:
