Replace everything in the js file with this:

Copyconst api_repo_url = "https://api.github.com/users/alisirri/repos";
fetch(api_repo_url, {
    headers: {
        authorization: "TOKEN",
    },
})
    .then((response) => response.json())
    .then((data) => {
        console.log(data);
    });

No need for async either as .then() takes care of that

Solution: In order to perform action on github api you can use curl according to Github doc:

1. first make sure you have specific privileges and authentication token generated to your account in order to interact with Github api:

profile Settings -> Developer Settings -> Personal access tokens -> Generate new token

2. the command should be in http PUT method on path /repos/:owner/:repo/contents/:path
3. The required params for editing or adding new files (according to api) message (String), Content (String) and sha(String), additional params are branch(String) commiter(String) and author(String)

Lets perform some curl message in order to perform your action, the simple formula for this case would be:

curl --user <userName>:<token>
--data '{"key":"value"}'
--header <HeaderType>
--request <HTTPMethod>
<fullURL>

for demonstration lets fill some details:

 curl --user johnDoe:abc123!@#
 --data '{"message":"my message","content":"my content","sha":"abcjfhtenf736gd843ji43903"}'
 --header Content-Type:application/json
 --request PUT
https://api.github.com/repos/MyOrganization/MyCoolApp/contents/app/models

4. Verify on Github the content has been inserted correctly to your branch
