I’m working on a project where I need to update an organization’s Google Drive token using OAuth2 authentication. My code works perfectly on my local machine, but when I deploy it to the server, I encounter an invalid error redirect_url. Here is the relevant part of my code:

def update_drive_gtoken(
    data: schema.UpdateDriveToken,
    sql: Session,
    auth_token: frontendModel.FrontendToken,
    organization: model.Organization
):
    """
    Update organization drive token
    """
    organization_user = sql.query(model.RegisterUserOrganization).filter_by(
        user_id=auth_token.user_id,
        org_uid=organization.id,
        is_active=True,
        is_deleted=False
    ).first()

    if not organization_user:
        CustomValidations.raize_custom_error(
            error_type="not_exist",
            msg="user does not belong to this organization"
        )

    token_json = None
    if auth_token.user_id == organization.admin_id:
        if data.code is not None:
            CLIENT_ID = "1234.com"
            CLIENT_SECRET = "FXXC"
            REDIRECT_URL = "http://localhost:3000"

            token_url = 'https://oauth2.googleapis.com/token'
            token_data = {
                'code': data.code,
                'client_id': CLIENT_ID,
                'client_secret': CLIENT_SECRET,
                'redirect_uri': REDIRECT_URL,
                'grant_type': 'authorization_code'
            }

            token_response = requests.post(token_url, data=token_data, timeout=80, verify=False)
            token_json = token_response.json()
            extracted_token = {
                'access_token': token_json.get('access_token'),
                'refresh_token': token_json.get('refresh_token'),
                'client_id': CLIENT_ID,
                'client_secret': CLIENT_SECRET,
                'expires_in': (datetime.utcnow() + timedelta(seconds=token_json['expires_in'])).isoformat(),
                'scope': token_json.get('scope'),
                'token_uri': token_url
            }

            if token_response.status_code != 200:
                CustomValidations.raize_custom_error(
                    error_type="invalid",
                    loc="code",
                    msg="Failed to exchange token. Please provide a valid Google token.",
                    inp=str(data.code),
                    ctx={"code": "valid"},
                )

            if organization.gtoken is not None:
                CustomValidations.raize_custom_error(
                    error_type="already_exist",
                    msg=f"token already exists in {organization.title}"
                )

            organization.gtoken = json.dumps(token_json)
            sql.commit()

            return {"organization": organization, "token": extracted_token}

When I run this code locally, the token exchange works without any issues. However, on the server, I get the following error message:”invalid redirect_url” I’m not sure why this mismatch is happening only in production. Has anyone faced a similar issue or knows how to resolve this? Any help would be greatly appreciated.
