Brownie not reading Account Private key from cinfiguration file

Question

I am using brownie to deploy the mart contract. But the brownie configuration file details is not accessing in deployment.py

brownie-config.yaml

project_structure:
    build: build
    contracts: contracts
    interfaces: interfaces
    reports: reports
    scripts: scripts
    tests: tests

dotenv: .env

wallets:
  from_key: ${PRIVATE_KEY}

networks:
    default: development
    development:
        gas_limit: max
        gas_buffer: 1
        gas_price: 70
        max_fee: null
        priority_fee: 60
        reverting_tx_gas_limit: max
        default_contract_owner: true
        cmd_settings: null

.env

export PRIVATE_KEY=0x<PRIVATE KEY> 

deployment.py

from brownie import project, Contract, accounts, config
import brownie

myproject = project.load('/home/ubuntu/Desktop/my_contract_local')
account = accounts.add(config["wallets"]["from_key"])
print(account)

This give me the following error

KeyError: 'wallets'

Update

I am executing this file using $ python deployment.py and not using $ brownie run deployment.py

Have you wrapped your private key in ' (single quotes) in the .env file like this?

export PRIVATE_KEY='a714b2b7xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
