Error: Checksummed addresses are not supported. Convert spenderAddress to lower case before passing when I call zeroEx.token.setProxyAllowanceAsync about 0x-monorepo

@capaj The only possible check that is failing here is value.toLowerCase() === value. Can you please try again with the following:

const txHash = await zeroEx.token.setProxyAllowanceAsync(
      this.address.toLowerCase(),
      walletStore.availableAddresses[0].toLowerCase(),
      ZeroEx.toBaseUnitAmount(amount, 18)
    )

If this doesn't work, can you please print out the values for this.address and walletStore.availableAddresses[0] that you are passing.

@fabioberger wehn I log those lines:

async setProxyAllowance(amount: BigNumber) {
    console.log('this.address.toLowerCase(): ', this.address.toLowerCase());
    console.log(' walletStore.availableAddresses[0].toLowerCase(): ',  walletStore.availableAddresses[0].toLowerCase());
    const txHash = await zeroEx.token.setProxyAllowanceAsync(
      this.address.toLowerCase(),
      walletStore.availableAddresses[0].toLowerCase(),
      ZeroEx.toBaseUnitAmount(amount, 18)
    )
    this.allowance = null

    await zeroEx.awaitTransactionMinedAsync(txHash)
    await this.getAllowance()
  }

I get:

this.address.toLowerCase():  0xef7fff64389b814a946f3e92105513705ca6b990
WalletToken.ts?b0aa:106  walletStore.availableAddresses[0].toLowerCase():  0x1b89831830f9d52efb92caff73283ac960b1f45f

ahh that's my tokenTransferProxyContractAddress from the initial ZeroEx config. Now I get it!

[capaj]

I tried to lowercase it in my config, but if I do that, I can't even fetch my tokens with getTokensAsync. It returns undefined.
So it would seems this needs to get fixed in here right?

[fabioberger]

Hm, zeroEx.tokenRegistry.getTokensAsync retrieves the tokens in the TokenRegistry smart contract. Sounds like an unrelated issue to me. What network are you running your code against? If TestRPC, are you migrating over the smart contract or running it from a snapshot?
