Error in Herok: problem with Binance Trade Bot with Python-Binance

As a developer of automated business robots using the Binance API interface, it is frustrating to encounter problems while trying to deploy your code on different platforms. In this article, we’ll dive into the mistake you are experiencing and provide solutions to help you solve.

Error:

The problem is due to the wrong pattern of the regex, which is used in your Python-Vinance client code. Specifically, the line regex._regex_core.error: A bad leak \ D in position 7 suggests that there is a problem with one of the signs in the regular expression used to process errors.

Basic information:

• Heroku is a cloud platform that provides an application environment to deploy applications.

• Python-Binance is an API client library that allows you to interact with the API Binance Exchange using the Python code.

• Exception regex._regex_core.error usually indicates that there is a problem with invalid use of nature in the regular expression.

Solution:

Step 1: Check and correct the regex pattern

In your Python-Mance client code, make sure you escape all the special features within the Regex pattern. Here are several suggestions to improve the regex pattern:

`Python

Import

Assuming this is your feature to create a Binance API client object:

Def Create_binance_client ():

… (the rest of the code remains the same)

error_regex = r “Invalid input:+\\ d $”

Return Re.compile (ERROR_REGEX)

Client = Create_binance_client ()

`

Step 2: Test your code

After making these changes, test your code to make sure it works as expected. You can do this:

• Creating a new file (eg test.py) and adding the following code:

`Python

to import pytest

from binance.client Import Client

From Datetsime Import Datetsme

Client = Create_binance_client ()

Define a few examples of data

Data = [“Hi, World!”, “This is invalid input”, “123”]

For an item in the data:

Try to launch the Binance API request with this item as an argument.

try:

client.get_account_balance (symbol = “btcusdt”)

Print (F “Error: {Item} was successful.”)

In addition to re.error as e:

Print (f “Error: {e}. Error Message Skip.”)

Start tests

If __name__ == “__main__”:

pytest.Main ()

`

• Save the file (eg test.py) and do it using python:

`Bash

python -m pytest test_test.py

`

This should output an empty console, suggesting that your code is running successfully.

Step 3: Upload your code to Heroku

After testing the code, you can upload it to Herok. Here is a detailed guide:

• Sign in to your Herok account and go to the dashboard.

• Click “New Edition” or “Put on Herok”.

• Choose the Python environment from the project settings (it should be set to use the “Python” interpreter).

• Create a new edition with the desired name, description and any additional information.

• Upload your code by clicking the Recent button.

Conclusion:

In this article, we have shown you how to identify and correct the error in the herok caused by the wrong patterns of regex when using Python-Binance. According to these steps, you should be able to solve the problem and successfully deploy your binance trade bot in Herok.
