ulamlabs / opennft Goto Github PK

Hi, I deployed OpenNFT and then I created an NFT following the guide in the Readme:

But I am getting a 503 response, with "not found" logs in the backend when I try to click on the NFT to get into the NFT view. This is what I visually get:

In the backend the logs show:

Request obtained with "Copy as fetch" from the Chrome Dev Tools:

  "referrerPolicy": "strict-origin-when-cross-origin",
  "body": null,
  "method": "GET",
  "mode": "cors",

});

This is how my NFT looks in the django admin:

Thanks in advance.

The method described in #7 can be extended to other OnComplete options, therefore the escrow account needs to check the value of the OnComplete field in SSC call transactions in the group.

As suggested. I am deploying backend on GCP and frontend on Vercel. But it is giving error of CORS policy on fromtend as backend and frontend are not on same server.
Can you please explain about it.
Thanks

Can you provide installation service?

Hey all, after running locally following the README, I managed to connect with my wallet, but then when I click deploy contract I get:

vuex.esm.js?2f62:542 Uncaught (in promise) {message: 'Validation failed for transaction because of invalid properties [group].'}

The head commit of master branch I'm using is e1b7e469aa1df99958d55e821dd673b281cdd620.

Steps to reproduce the issue:

1. connect wallet
2. create NFT

After the celery worker throws:

And the frontend enters to the #/admin/add-nft/f7b91685a185449e9ad77d699b78ea48?start=true where you can see the asset but then upon clicking Deploy Contract the message in the title of this issue is displayed in the console.

I tried to tweak the front end to see what is happening but couldn't do much. I found a more or less related topic https://forum.algorand.org/t/validation-failed-for-transaction-because-of-invalid-properties-group/5330.

I can't find the source of the error in the backend. Also not sure if the error in the front end is collateral, or if they are completely unrelated.

Environment: Ubuntu 20, Python 3.9.9, SQLite, PureStake credential correctly set. Some of the related transactions found in the explore. Happy to provide more details and try to help more. Thanks

I am having issue at the last step of creating NFT. Image is successfully uploaded to bucket but there is problem at deploy contract

The above exception was the direct cause of the following exception:

So I am testing locally and i see that the transactions cannot be signed

The JS error thrown is

Uncaught (in promise) Error: assetMetadataHash must be a 32 byte Uint8Array or string.
    at MyAlgoConnect.signTransaction (main.js?a441:341:1)

and I believe it has to do with the file /frontend/src/components/cards/AddAssetCard.vue

   metadataHash: assetUUID.replaceAll('-', '')

the uuid is not a correct format.

if I remove this the transaction is signed but I notice that the app is stuck on waiting for confirmation

Can't a registered user create and sell nft?

Hello,

First of all, amazing job on making this open source and available under MIT license !

I have a few questions on documentation:

1. Are you planning to release a more extensive documentation covering the codebase, file structure, architecture, local setup guideline and etc?
2. I believe the algobuilder related code in contracts folder are out of date, they have released v1.0.2 that has breaking changes. Pyteal code would still work but current setup is making local testing of contracts really hard, unless someone could document the setup guideline.
3. Is there a particular reason on why you are using a specific commit for a pyteal version in poetry file in contracts folder?

Would appreciate any reply on any of the above! Thanks in advance !

I'm trying to figure out why the creation cost is set how it is.

• OpenNFT/frontend/src/components/cards/AddAssetCard.vue

  Line 151 in e5622ce

  creationCost: 0.302 + 1.508 + 0.001 * 4

• https://developer.algorand.org/docs/get-details/dapps/smart-contracts/apps/#minimum-balance-requirement-for-a-smart-contract

The 1.508 amount in particular seems higher than necessary.

Any help would be appreciated.
