Lesson 8 - Error with provider and signer

[blackyinsol]

Hello everyone,

I am following lesson 8 and I am stuck with the first contract function: fund().

What is the problem?
I coded along with Patrick, but when I click on Fund (inside the webpage), nothing happens.

I checked what is going on with provider and signer with a console.log(), and I see that Patrick gets a different result than me with "signer". I get:

Object { _isSigner: true, provider: {…}, _index: 0, _address: null }
​
_address: null
​
_index: 0
​
_isSigner: true
​
provider: Object { _isProvider: true, disableCcipRead: false, anyNetwork: false, … }
​
<prototype>: Object { … }

But Patrick gets a provider: Web3Provider.

I also git cloned the repo, and still the same result. I am using Firefox web browser in Ubuntu 20.04.Anyone can help?

Could you list out every step you took until you got the error starting from scratch with a git clone?

I'm also not sure what your error is.

Hey Patrick! I repeated the steps and, somehow, now works!! Don't know why, maybe something I did wrong in the beginning and got a bug. I restarted my PC and tried again another day.

Thanks for your answer anyways! :D

9/10 redoing it from the start or trying to explain why it's broken, fixes it - welcome to programming ahah.

Was the error you got something to do with an unrecognised selector.
"Error: Transaction reverted: function selector was not recognized and there's no fallback function"
