Cannot verify source during contract deployment on SnowTrace

[aaron-cesaro]

Environment information

• brownie Version: 1.17.2
• ganache-cli Version: 6.12.2
• solc Version: 0.8.11
• Python Version: 3.10
• OS: linux

network not recognized using publish_source with SnowTrace API-KEY

I checked everything related to publish_source but seems that this isn't working properly.

Here's all relevant info about the code

brownie-config.yaml

dotenv: .env
wallets:
  from_key: ${PRIVATE_KEY}
networks:
  default: development
  avax-test:
    publish_source: True

.env [values are intentionally hidden]

export PRIVATE_KEY=0x3...XXXXX....53f
export WEB3_INFURA_PROJECT_ID=d8c556...XXXXX....f2fb
export ETHERSCAN_TOKEN=ADZZ...XXXXX....W739Z
export SNOWTRACE_TOKEN=DYH...XXXXX....W6J87

deploy.py

account = accounts.add(config["wallets"]["from_key"])
deploy_contract = TestContract.deploy(
            {"from": account},
            publish_source=config["networks"][network.show_active()].get(
                "publish_source", False
            ),

run command

brownie run deploy.py --network avax-test

brownie run deploy.py --network avax-test

"workaround" that i'm using so far: manually upload/verify source code on snowtrace testnet using Solidity Standard Json-Input

the necessary json file can be created using brownie (eg brownie console as shown below for a 'Registry' contract)

>>> import json
>>> with open('Registry.json','w') as f: f.write(json.dumps(Registry.get_verification_info()['standard_json_input']))
