Rust-Analyzer in VScode is failing "Cargo metadata fetch"

1

Hello everyone,

I am somewhat new to rust and still trying to understand how things work.

In my development setup I need to configure private crates registry and it will replace public crates.io. Things are working fine from the terminal including the (cargo metadata fetch) but it's failing when rust-analyzer in vs-code try to request metadata.

Looking at the error logs below cargo is complaining, not sure why it is behaving differently from terminal and within the vscode. Also more details here - Rust-analyzer in vs-code is failing to fetch "cargo metadata" · rust-lang/rust-analyzer · Discussion #14387 · GitHub

appreciate any kind of help.

Error log:
[ERROR rust_analyzer::main_loop] FetchWorkspaceError:
rust-analyzer failed to load workspace: Failed to read Cargo metadata from Cargo.toml file /xxxxxx/sd_monitor/Cargo.toml, Some(Version { major: 1, minor: 65, patch: 0 }): Failed to run cd "/xxxxxxx/sd_monitor" && "cargo" "metadata" "--format-version" "1" "--features" "" "--manifest-path" "/xxxxxx/sd_monitor/Cargo.toml" "--filter-platform" "x86_64-unknown-linux-gnu": cargo metadata exited with an error: error: failed to get hyper as a dependency of package sd_monitor v0.1.0 (/xxxxxx/sd_monitor)

Hello there,

I might be way-off, but I usually get that sort of error, when I do not add a linked project to .vscode/settings.json:

{
  "rust-analyzer.LinkedProjects": [
    "./relative-to-root/path/to/Cargo.toml"
  ]
}

Otherwise, I am out of ideas. Hope this helps

This didn't help, thanks for the suggestion.
