Hello! I'm getting an invalid hexlify value error whenever I try to sign this transaction. I'm at 7:19:15 in the video. https://youtu.be/gyMwXuJrbJQ?t=26355

Would appreciate any guidance. I already tried prefixing the private key with 0x but that did not help :(

Here's the full error.

Send the entire deploy.js.

You got it! I updated the post

You got it! I updated the post

Patrick only does it to explain the concept to us, ContractFactory should be the go-to generally. Also, if you really wanna do it just to test it out - the problem lies in data. The key should be encapsulated without the quotes " ". Hope this helps you!

[Brentably]

Ok so when defining tx I took the numbers out of quotes, and it ran, but I'm not sure why he specified in the video at 7:17:00 (https://youtu.be/gyMwXuJrbJQ?t=26220) that you should put the numbers in quotes...

[ThisisOat]

was stuck on this for a bit as well over the quote thing -_- maybe he says that so we can figure it out haha he is very sneaky

[MUHAMMAD-AMMAR-TANWEER]

Actually when I put the data in quotes and add 0x before it then it ran
https://youtu.be/gyMwXuJrbJQ?t=26640
Here you can see 0x is added in the data and data is in quotes

[Gennadion]

Hey! I had the same issue and realised the problem for me was that I used quotes in tx values. In the video for some reason it states to use quotes, while Patrick doesn't use them...

In your tx declaration remove the quotation marks ( ' ' ) for values in 'nonce', 'gasPrice', 'gasLimit' and 'value'.
So that code snippet should look like this:

const tx = {
    nonce: 2,
    gasPrice: 20000000000,
    gasLimit: 1000000,
    to: null,
    value: 0,
    data: [YOUR_BINARY],
    chainId: '1337'
  }
