Unable to connect with previously stored tokens (401)

[max-la-menacee]

Hello, I am currently trying to do first login with username/password and then use tokens stored in DB to connect but I get a 401. If anyone has an idea or could help me it would be greatly appreciated!!

def format_tokens_for_tokenstore(
    access_token,
    refresh_token,
    oauth_token,
    oauth_token_secret,
    scope,
    jti,
    token_type,
    expires_in,
    expires_at,
    refresh_token_expires_in,
    refresh_token_expires_at,
):
    if isinstance(expires_at, datetime.datetime):
        expires_at = int(expires_at.timestamp())
    if isinstance(refresh_token_expires_at, datetime.datetime):
        refresh_token_expires_at = int(refresh_token_expires_at.timestamp())
    oauth1_token = {
        "oauth_token": oauth_token,
        "oauth_token_secret": oauth_token_secret,
    }

    oauth2_token = {
        "access_token": access_token,
        "refresh_token": refresh_token,
        "scope": scope,
        "jti": jti,
        "token_type": token_type,
        "expires_in": expires_in,
        "expires_at": expires_at,
        "refresh_token_expires_in": refresh_token_expires_in,
        "refresh_token_expires_at": refresh_token_expires_at,
    }
    token_data = [oauth1_token, oauth2_token]
    tokenstore_string = base64.b64encode(json.dumps(token_data).encode()).decode()
    return tokenstore_string


tokens = get_user_tokens("id-bidon", connection=connect_to_db()) #Getting tokens from my DB
if not tokens:
    raise ValueError("No tokens found for user")

tokenstore = format_tokens_for_tokenstore(
    **tokens,
)

client = garminconnect.Garmin(email=None, password=None)
client.login(tokenstore=tokenstore)
activities = client.get_activities(0, 20)
