To resolve the issues with LangFlow failing to decrypt the API key and encountering JWT decoding errors, follow these steps:
-
Check Encryption and Decryption Utilities: Ensure that the
encrypt_api_keyanddecrypt_api_keyfunctions inauth_utilsare correctly implemented and configured. Thedecrypt_api_keyfunction should be able to successfully decrypt the stored API key using the correct settings. -
Verify JWT Token Structure: The error "Not enough segments" indicates that the JWT token might be malformed. Ensure that the JWT tokens are correctly generated with the required segments (header, payload, and signature).
-
Review the
get_settings_serviceConfiguration: Make sure that theSECRET_KEYandALGORITHMsettings are correctly configured in your environment. These settings are crucial for both encryption/decryption and JWT token management. -
Check the
get_current_active_userFunction: This function ensures that the user is active before proceeding with API key registration and JWT decoding. Verify that it is correctly implemented and that the user is indeed active. -
Error Handling and Logging: Review the error messages and stack traces provided by the
HTTPExceptionin thestore.pyandutils.pyfiles. These messages can provide insights into what might be going wrong.
Here are the relevant code snippets for reference:
Encryption and Decryption:
def encrypt_api_key(api_key: str, settings_service=Depends(get_settings_service)):
fernet = get_fernet(settings_service)
encrypted_key = fernet.encrypt(api_key.encode())
return encrypted_key.decode()
def decrypt_api_key(encrypted_api_key: str, settings_service=Depends(get_settings_service)):
fernet = get_fernet(settings_service)
encoded_bytes = encrypted_api_key.encode() if isinstance(encrypted_api_key, str) else encrypted_api_key
decrypted_key = fernet.decrypt(encoded_bytes).decode()
return decrypted_keyJWT Token Generation:
def create_token(data: dict, expires_delta: timedelta):
settings_service = get_settings_service()
to_encode = data.copy()
expire = datetime.now(timezone.utc) + expires_delta
to_encode["exp"] = expire
return jwt.encode(
to_encode,
settings_service.auth_settings.SECRET_KEY.get_secret_value(),
algorithm=settings_service.auth_settings.ALGORITHM,
)Error Handling in store.py:
def get_user_store_api_key(
user: User = Depends(auth_utils.get_current_active_user),
settings_service=Depends(get_settings_service),
):
if not user.store_api_key:
raise HTTPException(status_code=400, detail="You must have a store API key set.")
try:
decrypted = auth_utils.decrypt_api_key(user.store_api_key, settings_service)
return decrypted
except Exception as e:
raise HTTPException(status_code=500, detail="Failed to decrypt API key. Please set a new one.") from eBy ensuring that these components are correctly implemented and configured, you should be able to resolve the issues with API key registration and JWT decoding in LangFlow [1][2][3].

Bug Description
And I tried to register the Store API Key within this open LangFlow webpage. However, an error of 'API key save error. Could not validate credentials' occurred.
Reproduction
python -m langflow run
Expected behavior
I hope Store API Key will be approved.
Who can help?
No response
