More than one deposit triggers error, the reason ?
Hi .
I built and run the dbank, but I am just able to deposit one time . this means that if I start deposit for example 2 ETH, after completing the 2 ETH transfer, I am unable to do another deposit. I am getting error in this case .
Seems there is a problem in implementation, as a solution I should do one withdraw to solve the problem.
So say :
- 1 Deposit : successful
- 1 Deposit : Error
Triggers error for me, but :
- 1 Deposit : successful
- 1 Withdraw : successful
- 1 Deposit : successful
Any reason behind this?
To be sure about the code, I just cloned this repository for tests rather than the code I'm writing along with the youtube video tut.
Thanks.
