Make sure you check the response body itself. It should contain a more specific error indicating what the issue is.

    Response for the callout is:
    Error in call to API function "files/upload_session/append:2": The given OAuth 2 access token is malformed.

      That error message indicates that there's an issue with the access token value you're supplying with the API call. Check the access token you're sending and make sure you're using the exact value as it was provided to you by Dropbox. Don't add or remove any characters, make sure there's no stray whitespace, etc. (As a matter of security, do not share any access tokens or refresh tokens here.)

        Hi Greg, I looked into it and got to know that am not getting the Session_Id in the response of upload_session/start callout. So I tried hitting it with the following snippet:

                    "method": "post",
                    "headers": {
                        "Authorization" : "Bearer "+dropboxToken,
                        "Content-Type": "application/octet-stream",
                        "Dropbox-API-Arg": "{\"close\":false}"
                    },
                "body": file
                })
                .then((httpResponse) => {
                    console.log('Response:',httpResponse);
                    if (httpResponse.ok){
                        console.log("HTTP RES : OK")
                        return httpResponse.ok
                    } else {
                        console.log("HTTP RES : NOT OK")
                        return !httpResponse.ok
                    }                                  
                })
                .catch(err => console.log("[ERROR] UPLOAD_SESSION_FINISH : " + err));

        And even after status code of 200 am not getting any Session_Id, This is the response am getting:
        1. Response {type: 'cors', url: 'https://content.dropboxapi.com/2/files/upload_session/start', redirected: false, status: 200, ok: true, …}
