Common errors

error AttributeError: module 'compz' has no attribute 'CompZClient' ↓

cause Importing wrong symbol name after a failed installation or using an outdated version.

fix

Run 'pip install --upgrade compz' and verify import: from compz import CompZClient

error ValueError: Cannot submit attestation on mainnet without API key ↓

cause Attempting to use mainnet without providing an API key.

fix

Set environment variable COMPZ_API_KEY or pass api_key to constructor.

Warnings

gotcha The SDK defaults to mainnet. Always specify network='testnet' for development to avoid costly mistakes. ↓

fix client = CompZClient(network='testnet')

    network='testnet'

)
