Usually CORS error only indicate underlying error with the execution. Most probably it happens when the contract address is not verified or is one of non-supported networks.

In that case, you need to pass CONTRACT_ABI directly or DEFAULTS.abiCacheURL a URL from where to fetch ABI.

See here for details on how to do that: #22
