Method not allowed

[lauge-kongstad]

Hi I'm trying to follow your example but without success. The logs says it is trying to POST to webhook URL, but then right after it says that GET is not allowed. Any advice?

Task definition

    notify_teams_success = MSTeamsWebhookOperator(
        task_id='ms_team_notification',
        http_conn_id='msteams_webhook_url',
        message = f"Airflow: Dag {dag_name} finished succesfully.",
        subtitle = "What a **great** achievement.",
        theme_color = "00FF00",
        button_text = "Link to Airflow UI",
        button_url = "http://localhost:8080/admin/airflow/tree",
        #proxy = "https://yourproxy.domain:3128/",
        dag=dag
    )

I can post to my teams channel using the following code successfully using pymsteams pip package which uses requests library under the hood

import pymsteams
myTeamsMessage = pymsteams.connectorcard("https://maersk.webhook.office.com/webhookb2/xxx")
myTeamsMessage.text("Hello world")
myTeamsMessage.send()

This is the strange bit.

It's sending a POST but being rejected for sending a GET?

Is there something stripping the body out?

I noticed the message property is:

message = f"Airflow: Dag {dag_name} finished succesfully.",

Can you try removing the { } bit and test it normally first?

message = "Hello World",

Thanks for the reply, I'll give it a go and get back.

I have the same problem. I tried to remove { } but still not works.

[mendhak]

I am wondering if @lauge-kongstad maybe they found a solution?

Just making another guess. Could the problem be the http:// is the webhook somehow redirecting to its https:// version and that's causing an error.

Sorry for not getting back to you -- I went away from airflow, so haven't tried anything.
