Error returned when smart contract includes assembly code #65

Closed najienka closed 2 years ago

When ran against a smart contract that has some assembly code, the following error is returned. But commenting out the assembly code allows the tool to generate an SVG file as expected.

(node:22591) UnhandledPromiseRejectionWarning: VError: Failed to parse solidity file /contracts/ERC20_Asset_Pool.sol.: index parameter must be between >= 0 and <= number of children.

I tried a few contracts with assembly with the latest version and didn't get this error. Is there an example contract I can test against? Has your contract been deployed and verified on Etherscan?

Can reopen when there is an example to replicate this problem
