seems like it doesn't support etherjs's provider?

[newNcy]

im using etherjs and i want to use paraswap sdk but i found some function send transaction using web3 provider, for example approveToken actually i just need to know the approve that contract address. i prefer to use some interface like buildTx which did not depend on any other libs

the Paraswap.getSpender() pull a list of adapter on remote, but that list doesont have augustus.exchange property, so i got this err

can somebody expain the relationship of this list and the address to approve.
