Error when creating candy machine

[Baklaza]

Good evening! Guys, tell me. I enter the command into the console (all paths are specified correctly), this is how it looks:

ts-node C:\Users\Esh\Desktop\FortePiano\FortePianoSite\metaplex\js\packages\cli\src\candy-machine-v2-cli.ts upload -e devnet -k ~/.config/solana/devnet.json -cp C:\Users\Esh\Desktop\FortePiano\FortePianoSite\metaplex\js\packages\cli\config.json -c example C:\Users\Esh\Desktop\Assets

Throws this error:

Beginning the upload for 10 (img+json) pairs started at: 1641587507925 Size 10 { mediaExt: '.png', index: '1' } upload was not successful, please re-run.

What can be done about it? I will be very grateful for your advice, thank you!

It looks like there may be an error with your asset files. Would you mind posting what your 0.json file looks like?

Thank you for your feedback! File looks like this:

{ "name": "Forte & Piano #0", "symbol": "FP", "description": "description", "seller_fee_basis_points": 500, "image": "0.png", "external_url": "https://solflare.com", "attributes": [ { "trait_type": "Background", "value": "#D0FFEA" }, { "trait_type": "Piano Color", "value": "Mint" }, { "trait_type": "Element on piano", "value": "Bar-Stool White" }, { "trait_type": "Keyboard", "value": "Cups" } ], "collection": { "name": "Forte & Piano", "family": "Forte & Piano" }, "properties": { "creators": [ { "address": "3mZgKcZznBHtj6fYEgXh2T8he2vMb8J8LuK9bFKuwnLn", "share": 100 } ] } }

you're missing the files attribute in the properties array. Technically it isn't really needed though, and it shouldn't fail in the way it has. Check out our docs at https://docs.metaplex.com to view the metadata standard
