Ошибка выхода из Pytest, код 1 (действия github)

У меня есть репозиторий github с файлом Test_app.py. Я запускаю pytest для файла в действиях github и продолжаю получать сообщение об ошибке: E botocore.exceptions.NoRegionError: You must specify a region.

Затем я указываю регион в своем файле как: dynamodb = boto3.resource('dynamodb', region_name= 'eu-west-2'). И получаю следующую ошибку при выполнении pytest:

platform win32 -- Python 3.8.6, pytest-6.2.0, py-1.10.0, pluggy-0.13.1
rootdir: D:\a\cloudresumechallenge-BackEnd\cloudresumechallenge-BackEnd

============================ no tests ran in 0.31s ============================
Error: Process completed with exit code 1. 

Это мой лямбда-код:

import boto3
import json
dynamodb = boto3.resource('dynamodb', region_name= 'eu-west-2')
table= dynamodb.Table('zacresumetable2')

def lambda_handler(event, context):
    response= table.update_item(
    Key= {'URL': 'zacresume.com'},
    UpdateExpression= "SET visits = visits + :increase",
    ExpressionAttributeValues= {':increase': 1},
    ReturnValues= "UPDATED_NEW"
)
    return {'statusCode': 200,
            'body': json.dumps('visitsUpdated'),
            'headers': {'Content-Type': 'application/json'}}
print("UPDATING ITEM")
print("response") 

и это рабочий процесс для pytest:
