Lesson 6: API Key issues

[ArcusConsulting]

I generated my API key but my terminal says I have an invalid API key:

Windows 10 machine
Python 3.9.0

deploy.py

helpful_scripts.py

.env

etherscan.io

brownie-config.yaml

File tree:

Terminal:

Hey @ArcusConsulting I've reviewed your code and I didn't find anything wrong, however I have some suggestions for you.

1. Make sure your private key correspond to your Rinkeby address.
2. Sometimes brownie does not update the .env and you have to add those environment variables manually, so:
   • Close the project.
   • Open it again.
   • Delete the build folder
   • compile with: brownie compile
   • try to deploy again.
     This should load all the .env file again.
3. if nothing works, add the API key as environment variable manually through windows advanced configuration.

Final hint: Did you ever tried using WSL (windows subsystem for linux)? this would make your life easier, as if you want no add a new env variable to your path you just have to use export VARIABLE=value

Awesome... i did your Step 2 and it worked:

I'm a fish out of water with this stuff... I tried learning Python for the last 3 year and nothing has stuck. I use a few scripts for work (just deleting & combining PDFs) and am quite proficient with SQL, but this is a whole new world for me. I don't understand most of this 16h video, however I am fascinated by the Blockchain space and want to acquire a (future) highly in-demand skill. Thank you for taking the time to read over my code and having the patience to answer my questions.

Well being honest I also have just one month or so learning blockchain technologies and that's why I decided to help the community because all of this could be overwhelming so I'm glad my answers are helping you!

"if nothing works, add the API key as environment variable manually through windows advanced configuration."
I have added the infura ID and private key manually in user environment variable manually through windows advanced configuration. However, I am clueless how to fetch these in FundMe -Brownie lesson.
It works in local ganache. It is not getting deployed for testnet such as Rinkeby. Let me know how to load both variables to Eth-brownie project from advanced configuration please

@Anu-srinivasan, could you make a new discussion/ thread with as much detailed information as possible?

And yes, @cromewar is awesome :)

@Anu-srinivasan if you key is now on you OS variables you should use os.getenv() please refer to this

And thanks @PatrickAlphaC
