Indexer: Expected string or bytes-like object

Hello everyone, I’m trying to use the indexer for the first time, leaning on pure stake as a node. Whenever I try to get information from the indexer I always get the error like: expected string or bytes-like object. Would someone be able to explain to me why? Yet everything seems to me to be done.

Overspend account

Can you clarify in more detail, both how to use the goal network status command and how to synchronize local algod instance? Thank you.

I imported my account and set up testnet, but I always get the same overspend error. My code is this:

import json
import base64
from algosdk import account, mnemonic
from algosdk.v2client import algod
from algosdk.future.transaction import PaymentTxn

def generate_algorand_keypair():
    # Your implementation here

Hello everyone, I am trying to develop my first transaction on the Algorand blockchain. I created an account with the following address: 3YQ4XKUUELUN64C3PSV5BIF42BWOQ6V76X55IYHIJDOM6DRBO6A2A2BFVU. I have funded it and I can find the financing transaction and the account balance processed by Algorand.

Error: Socket Exception while trying to access kmd

Right now my node is installed via sandbox and with the curl command 127.0.0.1:4002/swagger.json I get a response like:

{
  "consumes": [
    "application/json"
  ],
  "produces": [
    "application/json"
  ],

  }
}

How can I implement this logic in the wallet itself, to be able to offer a multi-wallet functionality and therefore derive multiple addresses from the same mnemonic without going through kmd?

Goodmorning everyone, I am developing an Algorand Wallet on a Flutter mobile application in Dart. Right now I’m trying to connect to the kmd service of a node in order to get more addresses for a wallet from the same seedphrase. The node has started and kmd also but when I try to use the algorithm.

Error while installing pip3 install -r requirements.txt

I am trying to follow the tutorial I found on Developer Algorand but when I try to install the python development environment before I can run the example I get this error. Everything is installed correctly until at this point it finds problems with these packages.

Building wheel for pyteal...

Connection refused, errno = 111, address = localhost, port = 57838

My application is a wallet, everything works correctly and I have already developed the secure local archiving of the seedphrase. But what I’m trying to do now is to develop a feature that allows wallet users to create a multi-wallet wallet, with different addresses but linked to the same seedphrase.

Sorry for the duplication, I was looking for an answer… My intent is to derive multiple addresses from the same seedphrase, so kmd seemed the most suitable way to do this, am I wrong? Where can I also change the port number to use? This is the code of the CreateWalletRequestBuilder class:

class CreateWalletRequestBuilder:
    # Your implementation here

Kmd error: Connection refused, errno = 111, address = 127.0.0.1

How to connect a node to a mobile application?

Hello everyone, I am developing an application on Flutter in Dart, using an external API for Algorand. I am trying to use kmd to get new addresses but every time I try I get connection errors like: SocketException: OS error: connection refused.

Hi, this is the API I am using: GitHub - RootSoft/algorand-dart. The application I am developing on Android Studio with Flutter in Dart, no I am not currently using any node for testing. I usually use Docker sandbox.
