Error: *** Deployment Failed *** "Migrations" -- Web3ProviderEngine does not support synchronous requests

Hi,

I am facing this issue when deploying the flashloan contract to the mainnet.

Error: *** Deployment Failed ***

“Migrations” – Web3ProviderEngine does not support synchronous requests…

Kindly suggest.

Thanks

Seems like you were using an old version of the package.
