Fail to send http.post for creating new issue

Question

Hello, I'm using http REST API for creating a new issue inside my JSM space. When I'm sending the following curl command it works: curl --request POST --url 'https://my-domain.atlassian.net/rest/api/3/issue/' --user 'my-email:my-token' --header 'Accept: application/json' --header 'Content-Type: application/json' --data '{ "fields": { "project": { "id": "10001"} ,"issuetype": {"id": "10005" },"summary": "new test","description": {"version": 1,"type": "doc","content": [{ "type": "paragraph","content": [{"type": "text","text": "this is the description test"}]}]},"assignee": {"id": "712020:ca397ef3-d08a-4a36-9bf0-6bd230252ef6"},"reporter": {"id": "712020:ca397ef3-d08a-4a36-9bf0-6bd230252ef6"}}}' But when I'm trying to send it from my flutter app (FlutterFlow) it fails. I'm using it in the following way return http.post( Uri.parse('https://amigo-apps.atlassian.net/rest/api/3/issue/'), headers: { "Content-Type": "application/json", "Accept": "application/json", "Authorization": "Basic ${encoded}"}, body: jsonEncode( { "fields": { "project": {"id": "10001"}, "issuetype": {"id": "10005"}, "summary": "hello from flutterflow", "description": { "version": 1, "type": "doc", "content": [ { "type": "paragraph", "content": [ { "type": "text", "text": "hello from flutterflow -- description" }]}]}, "assignee": {"id": "712020:ca397ef3-d08a-4a36-9bf0-6bd230252ef6"}, "reporter": {"id": "712020:ca397ef3-d08a-4a36-9bf0-6bd230252ef6"} }},),);} My main problem is how to present the --user "email:token" being used inside the curl command in my app. Should it be inside the header option? ('authorization':'Basic ${base64(email:token)}) ? Should it be inside the body as a new line before the fields? Actually I've tried all options and failed with all. The error message I keep receiving is: Access to XMLHttpRequest at 'https://my-domain.atlassian.net/rest/api/3/issue/' from origin 'https://ff-debug-service-frontend-pro-ygxkweukma-uc.a.run.app' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. *I'm also tried using the atlassian flutter code inside pub.dev (https://pub.dev/packages/atlassian_apis) but it also didnt work. Thanks, Yuval

@Joseph Chung Yin  it was resolved. 
I was able to send it successfully by running the app from my android app instead from the web app using the browser.

The header being used was: '

"Authorization": "Basic ${encoded}"}",

Thanks

@Kuan Yi Ming (ServiceRocket)  you were right. 
It was a browser issue.
I've tested the flutter code in my android app and it worked.

I was able to create a JSM issue from my android app by sending http request.

The reason I'm a bit confused is , other API requests are being sent from the browser without any issues like this..

Anyway, thanks

Hi @Kuan Yi Ming (ServiceRocket) ,

Thanks for your reply.
No sure I understsnd, is this should be defined inside my header request like this:

Map<String, String> get headers => {

"Content-Type": "application/json",

"Accept": "application/json",

"Access-Control-Allow-Origin": "*",

"Authorization": ${email:token}

};

or, inside the browser network settings?
