How can i fix the gas price issue in Thirdweb Python SDK Goerli TestNet

Question

Im working with the Thirdweb Python SDK API. The code below sometimes work and sometimes throws a gasprice issue. I think it could be a network issue, because it works sometimes and generates the NFT but not always.

And when i got an error it is about gasprice. But in the Thirdweb API doesnt appear a gasprice argument or someting like this.

Any ideas?

Code:

    sqlcol="SELECT ID,(SELECT contrato FROM colecciones WHERE ID=idcolec) AS contratonft FROM solicitudcert WHERE ID='" + idsolicitud + "' LIMIT 0, 1"
    mycursor.execute(sqlcol)
    misolicitud = mycursor.fetchone()
    if(misolicitud):
        contratonft_aux=str(misolicitud[1])
        contratonft=contratonft_aux.replace('"','')
        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
        # You can pass in any address here to mint the NFT to
        tx = nft_collection.mint(NFTMetadataInput.from_json({
            "name": nombrecert,
            "description": descripcert,
            "image": urlarchivoimg
        }))
        idnft=tx.id
        return jsonify({'status':'OK','IDNFT':idnft})
    else:
        return jsonify({'status':'ERROR','IDNFT':"NULL"})

Error:

I tried to modify the contracts config into the thirdweb dashboard without success.

What network are you seeing this issue on? We can add in a method to manually overwrite gas limits in the SDK.
