[tokuhirom]

Thank you for reporting the urllib3.exceptions.NewConnectionError issue. This error typically arises when a connection to the server cannot be established. I've attempted to replicate the issue on our end but was unable to reproduce the error, which suggests the issue might be environment-specific.

Since we host the server you are trying to connect to, I have also checked its status and it appears to be functioning as expected. Here are some troubleshooting steps that might help:

1. Network Connectivity:

   • Ensure your network is stable. You might want to try pinging our server or accessing it through a web browser to check the connectivity.

2. Firewall/Security Settings:

   • Review your firewall and security settings to ensure they are not blocking the connection to our server.

3. Proxy Settings:

   • If you are behind a proxy, ensure it's correctly configured and operational.

4. SDK Configuration:

   • Verify the SDK is properly configured with the correct endpoint and credentials.

Please follow up with any additional information or if there's more you can provide to help diagnose this issue. We appreciate your cooperation and patience as we work to resolve this.

Thank you!

@tokuhirom I hosted this bot server/webhook on pythonanywhere and a slightly different variation with the old API worked fine but when I tested the V3 flask-kitchen it gave me this error.

below is the old API code that worked:

from flask import Flask, request, abort
from linebot import LineBotApi, WebhookHandler
from linebot.models import MessageEvent, TextMessage, TextSendMessage

# Your Line API credentials
CHANNEL_SECRET = "xxxx"
CHANNEL_ACCESS_TOKEN = "xxxx"

# Initialize the LineBotApi and WebhookHandler
line_bot_api = LineBotApi(CHANNEL_ACCESS_TOKEN)
handler = WebhookHandler(CHANNEL_SECRET)

app = Flask(__name__)

@app.route("/callback", methods=["POST"])
def callback():
    # Get the request body as text
    body = request.get_data(as_text=True)

    # Handle the Line event
    try:
        handler.handle(body, request.headers.get("X-Line-Signature", ""))
    except Exception as e:
        print(str(e))
        abort(400)

    return "OK"

@handler.add(MessageEvent, message=TextMessage)
def handle_message(event):
    user_id = event.source.user_id
    message_text = event.message.text

    if message_text.lower() == "info":
        # Get the user's profile
        profile = line_bot_api.get_profile(user_id)

        # Extract profile information
        user_id = profile.user_id
        display_name = profile.display_name
        picture_url = profile.picture_url
        status_message = profile.status_message

        # Send the user's profile information as a message
        response_message = f"User ID: {user_id}\nDisplay Name: {display_name}\n"
        response_message += (
            f"Profile Picture URL: {picture_url}\nStatus Message: {status_message}"
        )

        line_bot_api.reply_message(
            event.reply_token, TextSendMessage(text=response_message)
        )

hmm? I can run my bot with linebot.v3 on my machine. Here's a code with linebot.v3.

from flask import Flask, request, abort
from linebot.v3 import (
    WebhookHandler
)
from linebot.v3.webhooks import (
    MessageEvent,
    TextMessageContent,
)
from linebot.v3.messaging import (
    Configuration,
    MessagingApi,
    ReplyMessageRequest,
    ApiClient,
    TextMessage,
)

# Your Line API credentials
CHANNEL_SECRET = "xxxxx"
CHANNEL_ACCESS_TOKEN = "xxxxx"

# Initialize the LineBotApi and WebhookHandler
handler = WebhookHandler(CHANNEL_SECRET)
configuration = Configuration(
    access_token=CHANNEL_ACCESS_TOKEN
)

app = Flask(__name__)

@app.route("/callback", methods=["POST"])
def callback():
    # Get the request body as text
    body = request.get_data(as_text=True)

    # Handle the Line event
    try:
        handler.handle(body, request.headers.get("X-Line-Signature", ""))
    except Exception as e:
        print(str(e))
        abort(400)

    return "OK"

@handler.add(MessageEvent, message=TextMessageContent)
def handle_message(event):
    user_id = event.source.user_id
    message_text = event.message.text

    with ApiClient(configuration) as api_client:
        if message_text.lower() == "info":
            line_bot_api = MessagingApi(api_client)

            # Get the user's profile
            profile = line_bot_api.get_profile(user_id)

            # Extract profile information
            user_id = profile.user_id
            display_name = profile.display_name
            picture_url = profile.picture_url
            status_message = profile.status_message

            # Send the user's profile information as a message
            response_message = f"User ID: {user_id}\nDisplay Name: {display_name}\n"
            response_message += (
                f"Profile Picture URL: {picture_url}\nStatus Message: {status_message}"
            )

            line_bot_api.reply_message_with_http_info(
                ReplyMessageRequest(
                    reply_token=event.reply_token,
                    messages=[TextMessage(text=response_message)]
                )
            )

if __name__ == "__main__":
    app.run(debug=True)

@tokuhirom tried your version of the bot and gave me this error. May I know what Python version and package versions you used

By the way, what happens if you call the API with curl or other http client from your machine(or server) where you ran V3 flask-kitchen? We'd like to help you, but currently we can't produce your report.

[srikanthbojja]

@Yang-33 the webhook URL is receiving data from the bot

Request body: {"destination":"Ud2674e3166xxx","events":[{"type":"message","message":{"type":"text","id":"477953616574xx","quoteToken":"vV3CEteFTXi7C0x_ahndg1-iu8SIwkO0IA_yzF8-8oPlu9ZAi0h7kbK6PjFuLCUafLadES4BP6BTE8EtWGVtJKFWFx3z0YurEZq2m9B9EQTVq1V-xxx-OQ","text":"info"},"webhookEventId":"01HD3T3B2HAFZW4WYxxxx","deliveryContext":{"isRedelivery":false},"timestamp":1697713859533,"source":{"type":"user","userId":"U9e775e52373838c0aad209xxx"},"replyToken":"18e1cabafccb4ba8a3d61b22xxx","mode":"active"}]}

[be-hase]

What happens when you run this code snippet?

import urllib3
http = urllib3.PoolManager()
r = http.request('GET', 'https://api.line.me/oauth2/v2.1/certs')
r.status

[be-hase]

And this one.

import urllib3
urllib3.__version__

[srikanthbojja]

@be-hase

urllib3 version: 1.24.3

and the GETvrequest returns following error:

[be-hase]

Hmmm. If you are getting errors with this basic code, then something is wrong with your environment.

[srikanthbojja]

@be-hase I hosted this app on pythonanywhere.com and it tunnels the free users through a proxy "allowlist"

• api.line.me
• notify-api.line.me
• notify-bot.line.me
• api-data.line.me

are part of the allowlist, but still, I was not able to get traffic out even stranger thing is that the old API works but not the V3. Has something changed in V3?

https://help.pythonanywhere.com/pages/403ForbiddenError/

[Yang-33]

According to https://help.pythonanywhere.com/pages/403ForbiddenError/,

or that it needs to be configured to use a proxy.

I'm not sure this is related to your question or not, but probably you need to add configuration to use the proxy...?

like

configuration = Configuration(
    access_token=channel_access_token
)
configuration.proxy = "<PROXY_URL>"

[srikanthbojja]

@Yang-33

i tried

print(urllib3.__version__)
http = urllib3.ProxyManager('http://proxy.server:3128')
r = http.request('GET', 'https://api.line.me/oauth2/v2.1/certs')
print(r.__dict__)

and it returned

It seems like the error message has changed, hasn't it? If you have a moment, you might want to give it another try. I believe you'll see it too...

[srikanthbojja]

@Yang-33 you are right the error changed...but still not able to get the message pushed

[srikanthbojja]

@Yang-33 @be-hase @tokuhirom I upgraded urllib3 to 1.26.9 and Python to 3.10 and it works!!

I have a slightly different question, why do I see a max limit of 500 messages for my bot? Isn't Linebot free?

IS there some that needs to be changed in this code to remove the 500 limit

Here's a price table. https://www.lycbiz.com/jp/service/line-official-account/plan/

...But so , here's not a LINE official account's support channel. I will close this issue.
