Unable to expand environment vairable in host setting

Hello,
I am having trouble connecting to Infura API with Brownie. I’m new to coding.
I’m on Windows and I ran on PowerShell with .env activated:

set WEB3_INFURA_PROJECT_ID=[my project ID]
brownie console --network mainnet

I then get a series of error lines ending with:
raise ValueError(f"Unable to expand environment variable in host setting: ‘{uri}’")
ValueError: Unable to expand environment variable in host setting: ‘https://mainnet.infura.io/v3/$WEB3_INFURA_PROJECT_ID

I have tried creating a brownie-config.yalm file and adding dotenv: .env, but it did not change anything.

Does someone know what the problem might be? Thanks.

Hi cetel50, welcome to the forums!

Can we see the code you are using, esp. the part where you are accessing the env variable in your python code.
