If you’re trying to test a contract method that transfers any asset and your contract is compiling without any errors but your Rust test is failing, check to see if:

- your default toolchain is compatible with the version of fuels you are using
- you are appending variable outputs to the transaction: [Variable outputs - The Fuel Rust SDK](https://fuellabs.github.io/fuels-rs/v0.31.1/calling-contracts/variable-outputs.html?highlight=append_variable_outputs#variable-outputs)
