To resolve the "default credentials not found" error when using Vertex AI credentials on Windows 11 Pro with Langflow version 1.0.9 and Python 3.12, ensure that the credentials parameter is correctly set in the params dictionary. The initialize_vertexai function expects a path to the service account credentials file.
Here is an example of how you can set the credentials parameter:
params = {
"credentials": "path/to/your/service_account.json",
# other parameters
}
class_object = YourVertexAIClass # Replace with your actual class
initialized_object = initialize_vertexai(class_object, params)Make sure that the path to your service account JSON file is correct and accessible from your Windows 11 Pro environment. Additionally, ensure that the credentials parameter is set correctly in the build_config method of the VertexAIComponent class, as shown below:
class ChatVertexAIComponent(LCModelComponent):
display_name = "Vertex AI"
description = "Generate text using Vertex AI LLMs."
icon = "VertexAI"
def build_config(self):
return {
"credentials": {
"display_name": "Credentials",
"field_type": "file",
"file_types": [".json"],
"file_path": None,
},
# other parameters
}
def build(
self,
input_value: Text,
credentials: Optional[str],
project: str,
examples: Optional[List[BaseMessage]] = [],
location: str = "us-central1",
max_output_tokens: int = 128,
model_name: str = "chat-bison",
temperature: float = 0.0,
top_k: int = 40,
top_p: float = 0.95,
verbose: bool = False,
stream: bool = False,
system_message: Optional[str] = None,
) -> Text:
try:
from langchain_google_vertexai import ChatVertexAI # type: ignore
except ImportError:
raise ImportError(
"To use the ChatVertexAI model, you need to install the langchain-google-vertexai package."
)
output = ChatVertexAI(
credentials=credentials,
examples=examples,
location=location,
max_output_tokens=max_output_tokens,
model_name=model_name,
project=project,
temperature=temperature,
top_k=top_k,
top_p=top_p,
verbose=verbose,
)
return self.get_chat_result(output, stream, input_value, system_message)Ensure that the credentials parameter is correctly set in both the params dictionary and the build_config method. This should resolve the "default credentials not found" error [1][2][3].

Bug Description
Hello,
I do have strange error, I am using Windows 11 Pro, And while trying to use Credentials file on VertexAI, I am always getting
'Error Building Component Error building Component Vertex AI: Your default credentials were not found. To set up Application Default Credentials, see https://cloud.google.com/docs/authentication/external/set-up-adc for more information.'
Credentials are tested with flowise and other apps. They work. Maybe something is up with windows and this app and paths? Maybe there should be something like Credentials storage system for Credentials like in Flowise?
Thanks for help! a.
Reproduction
Use Basic prompt template. Replace OpenAI with Vertex AI model. Put in file with credentials.
Expected behavior
Error Building Component Error building Component Vertex AI: Your default credentials were not found. To set up Application Default Credentials, see https://cloud.google.com/docs/authentication/external/set-up-adc for more information.
