Hey @akantora

Please use the following command to overcome this issue.

truffle run verify {ContractName}@{ContractAddresss} --network polygon --debug

For Example:

truffle run verify SampleContract@0xa024Da234079331........E4 --network polygon --debug

As @mavvverick mentioned, providing the address manually is a good workaround. But auto-detection should generally work as well. Do you have a minimal repo where I can reproduce the issue?

[waqasideofuzion]

got the same issue and solved my problem with this command truffle run verify MyContract@address --network avalanche --debug

No reproduction repo was provided, so no way to debug this issue. Manually providing the address is a decent enough workaround. Closing this for inactivity.
