TransactionData

Moralis General
#1

Hello,
Whenever I am creating a TransactionData and adding value on TransactionData.data to send with EthSendTransaction to MetaMask and sending the metadata containing ABI and NFT metadata, it is returning the following: Cannot convert string to buffer.
What should I exactly send with data? Thank You!

Hi @bassel.l please add the related code and then the full error with the stacktrace. Also if you are following any docs, that would be helpful to further investigate.

#3

Can you please provide a Link for a proper Unity Documentation because I honestly can’t find any. Even after searching in the documentation for TransactionData type, nothing shows. Please send me a link where I can follow any documentation for unity. Meanwhile, I’ll be sending you the code

Thank you!

@bassel.l here is some documentation for Unity. Please post the code when you have a moment to understand more about the implementation you are using:

A possibility in Unity is to use HTTP requests directly to our endpoints using UnityWebRequest. Here are the corresponding docs and our swagger docs were you can find the API URLs:

– https://docs.unity3d.com/Manual/UnityWebRequest.html
– https://deep-index.moralis.io/api-docs/#/
– https://api.moralis-streams.com/api-docs/

Ok, so now instead of sending the TransactionData, I decided to follow the documentation that you’ve sent and figure out my way. First step of minting an NFT is to upload metadata to IPFS. Moralis provides a way of doing it, which is very simple:

        IpfsFileRequest ipfsFileRequest = new IpfsFileRequest(){ Path = name, Content = data};
        List<IpfsFileRequest> requests = new List<IpfsFileRequest> { ipfsFileRequest };

        List<IpfsFile> resp = await Moralis.GetClient().Web3Api.Storage.UploadFolder(requests);

The above very simple code, that can never go wrong, has resulted in the following error:

ApiException: Error calling UploadFolder: {“code”:141,“error”:"{“code”:“invalid_post_request”,“message”:“Invalid POST Request”}"}

Please let me know what could possibly go wrong with it. Thank you

Any Update on this matter?

Hi @bassel.l we are planning to remove IPFS. I recommend you to check Pinata instead: https://docs.pinata.cloud/sdks
