Error deploying echo-bot.py on Azure. ModuleNotFoundError: No module named 'aiohttp'

Question

I am following the Azure's tutorial on how to create and deploy a simple echo bot.

However, I have a problem when deploying. Here's the error:

I have found this SO but it did not solve my problem.

Here's my requirements.txt:

botbuilder_schema==4.13.0
gunicorn==20.1.0
aiohttp==3.6.3
botbuilder-integration-aiohttp==4.13.0
botbuilder-ai==4.13.0
botbuilder==0.0.1
botbuilder-core==4.13.0
botbuilder-dialogs==4.13.0

Here's my .deployment:

[config]
SCM_DO_BUILD_DURING_DEPLOYMENT = true

Here are the files inside of my root folder:

README.md
init.py
app.py
bot.py
config.py
deploymentTemplates
requirements.txt
.deployment
.env

And here's the command I am using to deploy the bot: az webapp deployment source config-zip --resource-group "resource_name" --name "service_name" --src "echo-bot.zip"

Please help!

I was getting the same no module namedaiohttp found error locally due to version incompatibility.

Follow below steps to deploy echo bot application.

I have created a python echo bot project with Python 3.9 version and able to run locally.

Create and activate virtual environment

py -m venv env
.\env\Scripts\activate

Added below packages in requirements.txt

botbuilder-integration-aiohttp>=4.14.0
aiohttp
botbuilder-core
botbuilder-schema

Install required dependencies

pip install -r requirements.txt

Local Response:

enter image description here

To deploy the application to Azure, add init_func() to app.py and modify the code as below:

import sys
import traceback
from datetime import datetime
from aiohttp import web
from aiohttp.web import Request, Response, json_response
from botbuilder.core import (BotFrameworkAdapter, BotFrameworkAdapterSettings,
                             TurnContext)
from botbuilder.core.integration import aiohttp_error_middleware
from botbuilder.schema import Activity, ActivityTypes

from bot import MyBot
from config import DefaultConfig

CONFIG = DefaultConfig()

SETTINGS = BotFrameworkAdapterSettings(CONFIG.APP_ID, CONFIG.APP_PASSWORD)
ADAPTER = BotFrameworkAdapter(SETTINGS)

async def on_error(context: TurnContext, error: Exception):

    print(f"\n [on_turn_error] unhandled error: {error}", file=sys.stderr)
    traceback.print_exc()

    await context.send_activity("The bot encountered an error or bug.")
    await context.send_activity(
        "To continue to run this bot, please fix the bot source code."
    )

    if context.activity.channel_id == "emulator":

        trace_activity = Activity(
            label="TurnError",
            name="on_turn_error Trace",
            timestamp=datetime.utcnow(),
            type=ActivityTypes.trace,
            value=f"{error}",
            value_type="https://www.botframework.com/schemas/error",
        )
        await context.send_activity(trace_activity)

ADAPTER.on_turn_error = on_error

# Create the Bot
BOT = MyBot()

# Listen for incoming requests on /api/messages
async def messages(req: Request) -> Response:
    # Main bot message handler.
    if "application/json" in req.headers["Content-Type"]:
        body = await req.json()
    else:
        return Response(status=415)

    activity = Activity().deserialize(body)
    auth_header = req.headers["Authorization"] if "Authorization" in req.headers else ""

    response = await ADAPTER.process_activity(activity, auth_header, BOT.on_turn)
    if response:
        return json_response(data=response.body, status=response.status)
    return Response(status=201)
    
# enclosing the below code with init_func()

def init_func(argv):
    APP = web.Application(middlewares=[aiohttp_error_middleware])
    APP.router.add_post("/api/messages", messages)
    return APP
if __name__ == "__main__":
    APP = init_func(None)

    try:
        web.run_app(APP, host="0.0.0.0", port=CONFIG.PORT)
    except Exception as error:
        raise error

Create an Azure Bot with Multi Tenant and Python Azure app service.
Open your Azure Bot and add the Web App's URL with /api/messages i.e.,(https://<webappname>.azurewebsites.net)in the Azure Bot=>COnfiguration=>Message Endpoint.
Get the Microsoft App ID and create a secret to use its value as Microsoft App Password from the Azure Bot=>Configuration.
Update the Microsoft App ID and Microsoft App Password values in Config.py:

class DefaultConfig:
    """ Bot Configuration """
    PORT = 3978
    APP_ID = os.environ.get("MicrosoftAppId", "a573434f-3b7b-4e52-919a-c574d56965b5")
    APP_PASSWORD = os.environ.get("MicrosoftAppPassword", "mWk8Q~.6uGbHAvNzBlg3T6kikKfPUCaC7HV~sdpW")

Deploy the Application to Azure.

enter image description here

After deploying the application, add the Startup command in theAzure App Service=>Configuration=>General settings:

python3 -m aiohttp.web -H 0.0.0.0 -P 8000 app:init_func

enter image description here

Test the Bot:

Go to your Azure Bot=>Settings=>Test in Web Chat and test the chat bot as below:

Thank you for your help! However I am still getting one error:

2024-02-16T08:32:29.267514758Z /tmp/8dc2ec96872817f/antenv/bin/python3: Error while finding module specification for 'aiohttp.web' (ModuleNotFoundError: No module named 'aiohttp')

It seems that it is not running pip install -r requirements.txt?

Pravallika KV Over a year ago

Which version of python are you using?

João Abrantes Over a year ago

I am using python 3.11 (I saw that you were using the same from your screenshot). Are you uploading your venv folder? –

Pravallika KV Over a year ago

Yes, I have uploaded it.

João Abrantes Over a year ago

It works! My zip add an extra folder. It was root/contents and it should be just contents. Thank you very much!
