MetaMask - RPC Error

[BlackH3art]

Hey Gregory,

I'm running to an issue in 2:23:30 of this tutorial, when it comes to test staking.
After I approve spending token, metamask shows me an error:

And after I confirm that in MetaMask console displays me this error:

I was writing all the contract code on my own (TokenFarm.sol), but then I just copied this from repository, compiled it, and still running to the same issue.

Any idea about how to fix this error?

going through this issue as well, one of the transactions worked, but now it's just doing this. I read that you can delete the json from the contracts and recompile them

[Jbry123]

i solved it by clearing the json, truffle compiling, and connecting ganache by adding the truffle config file to ganache's desktop app

Which json are you clearing?

Hi,
I had the same problem, it was to do with a time out. Try changing the stake method to async like this:-

stakeTokens = async (amount) => {
this.setState({ loading: true })
await this.state.daiToken.methods.approve(this.state.tokenFarm._address, amount).send({ from: this.state.account })
await this.state.tokenFarm.methods.stakeTokens(amount).send({ from: this.state.account })
this.setState({ loading: false })
}
