Rust client for Twilio's API example program error - rust

Question

I am trying to get this exercise to run but keep getting a (permissions?) error on my AccountSid, which should be correct.
thread 'main' panicked at 'Something went wrong, ResponseError(ResponseContent { status: 401, content: "{\"code\": 20003, \"detail\": \"Your AccountSid or AuthToken was incorrect.\", \"message\": \"Authentication Error - invalid username\", \"more_info\": \"https://www.twilio.com/docs/errors/20003\", \"status\": 401}", entity: Some(UnknownValue(Object({"code": Number(20003), "detail": String("Your AccountSid or AuthToken was incorrect."), "message": String("Authentication Error - invalid username"), "more_info": String("https://www.twilio.com/docs/errors/20003"), "status": Number(401)}))) })'
Initially, I got a "this function takes 21 arguments but 18 arguments were supplied" error but fixed it by supplying the correct amount of None arguments to twilio_api::create_message
After that I get this AccoutSid error.
Here is the walk-through: https://www.twilio.com/docs/openapi/generating-a-rust-client-for-twilios-api
And here is my code for the exercise. I have the .env filled out correctly.
use dotenv;
use openapi::apis::{configuration::Configuration, default_api as twilio_api};
use std::env;
#[tokio::main]
async fn main() {
// Securely import sensitive credentials and values from `.env` instead of inlining their values.
dotenv::dotenv().expect("Failed to read .env file");
let account_sid = env::var("TWILIO_ACCOUNT_SID").expect("Failed to parse Account SID");
let api_key = env::var("TWILIO_API_KEY").expect("Failed to parse API Key");
let api_key_secret = env::var("TWILIO_API_KEY_SECRET").expect("Failed to parse API Key Secret");
let from = env::var("TWILIO_PHONE_NUMBER").expect("Failed to parse 'from' number");
let to = env::var("TO_NUMBER").expect("Failed to parse 'to' number");
// Create a new, default client configuration.
let mut twilio_config = Configuration::default();
// Apply your Basic Auth credentials to the client configuration.
twilio_config.basic_auth = Some((api_key, Some(api_key_secret)));
// Asynchronously send the message "Ahoy, Rustacean! 🦀" to the `to` number from your Twilio phone number.
let message = twilio_api::create_message(
&twilio_config,
&account_sid,
&to,
None,
None,
None,
Some("Ahoy, Rustacean! 🦀"),
None,
None,
Some(&from),
None,
None,
None,
None,
None,
None,
None,
None,
None,
None,
None,
)
.await;
let result = match message {
Ok(result) => result,
Err(error) => panic!("Something went wrong, {:?}", error),
};
// Once successful, print out the SID of the sent message.
println!("{:?}", result.sid);
}

Just got through the same error:
Install cargo-edit like the doc recommends, and use cargo add to download the crates. This resolved my error.
After that I had another issue with the parameters given in the example code, so I changed it like this:
let body = "SMS test was successful!".to_string();
let message = twilio_api::create_message(
&twilio_config, // 1
&account_sid, // 2
&to, // 3
None, // 4
None, // 5
None, // 6
None, // 7
None, // 8
None, // 9
None, // 10
None, // 11
None, // 12
None, // 13
None, // 14
None, // 15
None, // 16
None, // 17
Some(&from), // 18
None, // 19
Some(&body), // 20
None, // 21
)
.await;
