len(advancedCollectible) -1 out of range

[snowyaya]

Hi,
I was trying to run the create_metadata.py, but got the error saying the len(Advanced_Collectible)-1 is out of range. More details of the error is shown as below.

I tried to pin the file to Pinata, which was successful, but not sure why Advanced_Collectible doesn't contain anything.
Any idea of the reason?

Brownie v1.17.2 - Python development framework for Ethereum

NftMixProject is the active project.

I actually found this line from create_metadata.py
advanced_collectible = AdvancedCollectible[len(Advanced_Collectible)-1]
is actually written as
advanced_collectible = AdvancedCollectible[-1] in the lecture.

Are there any difference? I tried both, but still have the same issue.

I actually figured it out. It works now by just following what you did in the lecture.

1. change from advanced_collectible = AdvancedCollectible[len(Advanced_Collectible)-1] to advanced_collectible = AdvancedCollectible[-1]
2. change the breed_to_image_uri to

breed_to_image_uri = {
    "PUG": "https://ipfs.io/ipfs/QmSsYRx3LpDAb1GZQm7zZ1AuHZjfbPkD6J7s9r41xu1mf8?filename=pug.png",
    "SHIBA_INU": "https://ipfs.io/ipfs/QmYx6GsYAKnNzZ9A6NvEKV9nf1VaDzJrqDR23Y8YSkebLU?filename=shiba-inu.png",
    "ST_BERNARD": "https://ipfs.io/ipfs/QmUPjADFGEKmfohdTaNcWhp7VGk26h5jXDA7v3VtTnTLcW?filename=st-bernard.png",
}

So how can I help to revise the code in the repo?

[PatrickAlphaC]

Awesome! Thanks for making these issues!

I think maybe it would be wise to maybe add some print statements throughout the repo to help people who get stuck...

Or are you saying the code you're using is different than the code in this repo?

[snowyaya]

@PatrickAlphaC The code I am using is different from this repo..

[PatrickAlphaC]

Ah... ok! Could you make a PR showing what you changed to help fix this one?

Interesting that working with https://ipfs.io/ipfs is working over ipfs://.... Might be something with your local ipfs node or something...

Hi @PatrickAlphaC! I just created the pr for this issue and the issue in #93. I think you did https://ipfs.io/ipfs in the lecture.
