fix: add configurable proxy timeout for source network fetches - #184
Merged
Conversation
When cloning smart contract addresses from mainnet, storage fetch times out with 'Read timed out. (read timeout=5)' on gateway.multiversx.com/address/.../keys. The default ProxyNetworkProvider timeout of 5 seconds is too short for large contract storage. - Add PROXY_TIMEOUT config parameter (default 10s, mainnet 30s, chain simulator 60s) - Create _build_source_proxy() helper to apply timeout to source network fetches - Update MyProxyNetworkProvider to use configured timeout for local proxy - Timeout now applies to: account cloning, storage fetching, ESDT module lookups
