Issue on npm start after deploying contract to ropsten testnet #3

Open ericscottmarquez opened 2 years ago

ericscottmarquez commented 2 years ago

I have successfully deployed the contract on the Ropsten test network.

0x582C29C954f4C6dB9D63Ab16b80a0b17Ea4174E6

When running npm start, I receive this error stating that the getPair function may be having an issue? I have the index.js file configured as default from the repository. Seems that the script index.js is failing in the provider.on("block", async (blockNumber) => { try block, but I can't sort out exactly why this error is occurring. Any help is greatly appreciated, and thanks for putting this code out there!

$ npm start

Error:
