Client must be authenticated to access this resource. jira rest api - node.js

Question

I've created a project using node module passport-atlassian-oauth2 and i get the accessToken successfully. But when I do a request to create an issue I get the error
Client must be authenticated to access this resource.
Below is my code for create issue jira api.
Could you help please?
var bodyData = {
"fields": {
"project": {
"key": "FLUX"
},
"summary": "REST ye merry gentlemen.",
"description": "Creating of an issue using project keys and issue type names using the REST API",
"issuetype": {
"name": "Bug"
}
}
};
var baseUrl = 'https://alamrezoanul.atlassian.net';
var options = {
method: 'POST',
url: `${baseUrl}/rest/api/3/issue`,
data: JSON.stringify(bodyData),
headers: { 'Authorization': 'Bearer ' + jiraTokens.accessToken, 'Content-Type': 'application/json' },
json: true };
axios(options)
.then((response2) => {
console.log("response2.data: ", response2.data);
})
.catch((error) => {
console.log("error: ", error);
})

Answer 1

Hi I encountered the same issue today. You need to fetch the cloud id of https://alamrezoanul.atlassian.net and then instead of doing var baseUrl = 'https://alamrezoanul.atlassian.net'; use var baseUrl = 'https://api.atlassian.com/ex/jira/{cloud id}';.
You can fetch the cloud id by doing a authenticated GET request to https://api.atlassian.com/oauth/token/accessible-resources.

You might want to check the audience in your authorised tokens.
https://developer.atlassian.com/cloud/jira/platform/oauth-2-authorization-code-grants-3lo-for-apps/#implementing-oauth-2-0--3lo-
Setup says:
audience: (required) Set this to api.atlassian.com.
You may need to set to alamrezoanul.atlassian.net

Same issue I have fixed instead username and password use email and api token link to generate token
Below code I am using in my project
public String getEncodedAuth() {
String username = "user#gmail.com";//enter your mail
String auth_header = username + ":" + "<API token>";
String encodedAuth = Base64.getEncoder().encodeToString(auth_header.getBytes());
return encodedAuth;
}
public void getIssue(String issueId) {
Response response = RestAssured.given()
.header("Authorization", "Basic " + getEncodedAuth())
.contentType(ContentType.JSON)
.pathParam("issueIdOrKey", issueId)
.queryParam("fields", "attachment")
.when()
.get("https://user.atlassian.net/rest/agile/1.0/issue/{issueIdOrKey}");
response.prettyPrint();
}
