Issue Creation Failed --: Request failed. Please analyze the request body for more details. Status code: 400

I am able to successfully connect to My JIRA cloud and pulled in the details of an issue even transition is also happening of existing tickets. I am trying to just create a new issue with the example provided (https://github.com/andygrunwald/go-jira/blob/master/examples/create/main.go) but it's failing with the error: ```2022/02/06 21:38:47 request failed. Please analyze the request body for more details. Status code: 400```.

Here is the code I am using:

```
package main

import (
"log"
"os"
"fmt"
"github.com/joho/godotenv"
jira "github.com/andygrunwald/go-jira"
)

func main() {
// Load the .env file
godotenv.Load(".env")
// Create a BasicAuth Transport object
tp := jira.BasicAuthTransport{
Username: os.Getenv("JIRA_USER"),
Password: os.Getenv("JIRA_TOKEN"),
}
// Create a new Jira Client
client, err := jira.NewClient(tp.Client(), os.Getenv("JIRA_URL"))
if err != nil {
log.Fatal(err)
}
i := jira.Issue{
Fields: &jira.IssueFields{
Assignee: &jira.User{
Name: "myuser@domain.com",
},
Reporter: &jira.User{
Name: os.Getenv("JIRA_USER"),
},
Description: "Test Issue",
Type: jira.IssueType{
Name: "Task",
},
Project: jira.Project{
Key: "Infra",
},
Summary: "Just a demo issue",
},
}
createIssue, _, err := client.Issue.Create(&i)
if err != nil {
log.Fatal(err)
}
fmt.Printf("%s: %+v\n", createIssue.Key, createIssue.Fields.Summary)
}
```

I receive the following error every time
```2022/02/06 21:38:47 request failed. Please analyze the request body for more details. Status code: 400```
My JIRA_USER account has administrator privileges. I am using JIRA cloud.

Could you give me a good example or assist me on this? Also possible to get any user's ccountID with this module??
