Repay issue in web3js-example

[alrevuelta]

Hi, I'm playing around with this example and have successfully managed to run deposit and borrow, but I'm getting an error when running Repay.

Here is what I get:

Error repaying in the LendingPool contract: Transaction has been reverted by the EVM:

I'm using Kovan, replacing lpAddressProviderAddress and daiAddress variables with the following values respectively:

• LendingPoolAddressesProvider: 0x506B0B2CF20FAA8f38a4E2B524EE43e1f4458Cc5
• DAI: 0xFf795577d9AC8bD7D90Ee22b6C1703490b6512FD

Apart from that, I edited the amounts (1000 by default) to the following ones:

• Deposit 20. After the deposit, I can see 20 aDAI in my account and -20 DAI.
• Borrow 5. Then I can see +5 DAI.
• Repay 5. But get the error abvove.

Even if I automatically repay with -1 I get the same error.

Am I doing something wrong? I haven't done any other modifications apart from the mentioned ones.
