ERROR: Error invoking `cargo metadata` when trying to compile INK! 4.0 smart contract

Question

When I compile a specific INK! 4.0 smart contract i get the following error: ERROR: Error invoking `cargo metadata

I have multiple INK! 4.0 smart contracts that are compiling successfully without the above error, i even copy and pasted the Cargo.toml file of the working contracts but Im still getting the above error.

Here's how my Cargo.toml file looks like:

If you are using latest ink i.e. 4.0.0-beta and latest openbrush, then you have to change little bit in Cargo.toml file.

1. use this for ink package: ink = { git = "https://github.com/paritytech/ink", rev = "4655a8b4413cb50cbc38d1b7c173ad426ab06cde", default-features = false }

2. use version = "2.3" for scale_info: scale-info = { version = "2.3", default-features = false, features = ["derive"], optional = true }

3. for openbrush use tag instead version: openbrush = { tag = "3.0.0-beta", git = "https://github.com/727-Ventures/openbrush-contracts", default-features = false, features = ["psp34"] }
