What's the full error message?

[vocal plover]

Try passing in the api key that you get as a named parameter? I'm not sure how nicely pydantic plays with a google colab environment

[trail agate]

So just directly paste the key as a parameter?

[loud mauve]

I think your env var has the wron name

from the error message, it's looking for TAVILY_API_KEY

but your env vars are just TAVILY_KEY and API_KEY

[vocal plover]

Yeah something like

api_key = userdata.get(...)

...

web_search_tool = TavilySearchResults(k=3, tavily_api_key=api_key)

[trail agate]

where did you guys find a tavily_api_key?

import os, getpass
from google.colab import userdata
userdata.get('TAVILY_KEY')
userdata.get('LANGSMITH_KEY')
def _set_env(var: str):
  if not os.environ.get(var):
    os.environ[var] = getpass.getpass(f"{var}: ")

_set_env("TAVILY_KEY")
_set_env("LANGSMITH_KEY")

os.environ['TOKENIZERS_PARALLELISM'] = 'true'
os.environ["LANGCHAIN_TRACING_V2"] = 'true'
os.environ["LANGCHAIN_PROJECT"] = "local-llama32-rag"

###Search
from langchain_community.tools.tavily_search import TavilySearchResults
web_search_tool = TavilySearchResults(k=3)

###LLM
from langchain_ollama import ChatOllama
local_llm = 'llama3.2:3b-instruct-fp16'
llm = ChatOllama(model=local_llm, temperature=0)
llm_json_mode = ChatOllama(model=local_llm, temperature=0, format='json')```

From the error message

[trail agate]

i know, but shouldnt it then be in my code?

if i've written a variable wrong

[vocal plover]

The error message is telling you what it should be

[loud mauve]

Rename TAVILY_KEY to TAVILY_API_KEY

[trail agate]

huh. why does that matter?

is it not just a variable

[loud mauve]

As indicated by the error message, this is the env var in which it's looking for the api key

It also suggests passing it in as a named param, as jim already mentioned too

[vocal plover]

For environment variables, programs will look for a specific name to look up

[trail agate]

Yeah i just read it properly, but its weird why i have to name it in a certain format in a secrets file

[trail agate]

i understand

it works, thanks a lot guys

[loud mauve]

Why is that weird? The library you're using can't just guess out of all the environment variables which one to use

[trail agate]

i mean i can name it xyz and then if i say to detect xyz, for the value of the key, isn't that normal?

[vocal plover]

But in your code you didn't tell it to look for a different env car name. So it's still looking under the original one

Some programs do allow you to set which env var name it should look under, but it's more common for it to just expect it under one name and nowhere else

[trail agate]

i named it TAVILY_KEY in the folder and even here in the code i passed TAVILY_KEY everywhere for the same environment variables. Shouldn't it detect that?

[trail agate]

Yeah that's what im saying, so this is like either a colab or a tavily's own formatting way of naming keys this way right?

[loud mauve]

You never told the authentication library what the name of your environment variable was

All it knows is to look for "TAVILY_API_KEY"

[vocal plover]

How is TavilySearchResults() supposed to know that though? You also set Langsmith Key, why shouldn't it also look under there?

[vocal plover]

This is Tavily requiring a specific name for the env var it will search under

[trail agate]

cus tavilysearchresults() didn't ask for a key directly and even when it requires one it can look up tavily_key from here? (Now i changed it ofc)

[trail agate]

Hmm yeah then its something i need to keep in mind

[vocal plover]

But it's looking under tavily_api_key. It has no way to know to search for something else

[trail agate]

is it like tavily_api_key is the default term its searching for? And if i want to change that i need to add additional commands or something?

[vocal plover]

Yeah, but most libraries won't let you change the term it'll look for. It just tells you what the name to set and that's just what you have to do

[trail agate]

ahh okay okay i understand. Thanks!
