How can I fix Thirdweb Goerli Testnet HTTP Error 429?

Question

I'm minting the NFT with the Python SDK of Thirdweb using Goerli TestNet.

Code :

sdk = ThirdwebSDK.from_private_key(PRIVATE_KEY, NETWORK)
NFT_COLLECTION_ADDRESS = contratonft
nft_collection = sdk.get_nft_collection(NFT_COLLECTION_ADDRESS)
urlarchivoarr=imagencert.split("/")
urlarchivostr=str(urlarchivoarr[1]);
urlarchivoimg="https://files.avfenixrecords.com/" + urlarchivostr
metadata=NFTMetadataInput.from_json({
    "name": nombrecert,
    "description": descripcert,
    "image": urlarchivoimg
})
# You can pass in any address here to mint the NFT to
# xxxxx is the goerli wallet
tx = nft_collection.mint_to("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", metadata)
receipt = tx.receipt
token_id = tx.id
nft = tx.data()
idnft=tx.id

Error:

I thought it was a cache or temporary issue of Thirdweb but it persists. I changed :

tx = nft_collection.mint(metadata)

to

tx = nft_collection.mint_to("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", metadata)

without success.

Answer 1

What version of the Python SDK are you using? I would suggest upgrading to the latest version (2.1.0).

This issue looks like its coming up because your SDK is still using the old public alchemy RPC endpoint, which has since been shut down/blocked.

We updated our SDK to use different RPC endpoints in later versions which should be working still.
