Event with signature 'WethSet(indexed address)' not present in ABI 'AaveOracle'.

Hi, i try to run command
# run codegen npm run subgraph:codegen
And then give me error.

Failed to load subgraph from subgraph.yaml: Error in subgraph.yaml:
Path: dataSources > 0 > eventHandlers > 2
Event with signature 'WethSet(indexed address)' not present in ABI 'AaveOracle'.
Available events:

• AssetSourceUpdated(indexed address,indexed address)
• BaseCurrencySet(indexed address,uint256)
• FallbackOracleUpdated(indexed address)
• OwnershipTransferred(indexed address,indexed address)

if i delete lines (41-42) in the file subgraph.yaml
event: WethSet(indexed address)
handler: handleWethSet

Then the command works without errors
However, if further I try to enter -
npm run deploy:self-hosted:kovan || npm run deploy:self-hosted:mainnet
or npm run deploy:hosted:kovan || npm run deploy:hosted:mainnet

But when you call this command, a new file is generated this bug strings
Any idea how can i fix that ?

it seems like the contract was updated and 'WethSet' isn't available anymore. aave/protocol-v2@0e7bc49#diff-3eb91bbed0969b7a39be2c39095e2ed0edf70f570f9170e779b5ecfbd5ea5430

For anybody that hits this issue, you could reset history in the v2 submodule:

cd externals/protocol-v2
git reset --hard d460ab4e # the commit before the WethSet change
cd ../../
yarn submodule:compile-contracts
yarn prepare:subgraph

I could deploy the subgraph with this little change. Waiting now for graph sync, hope everything works 🙏
