There is an bug in

prefect/src/prefect/blocks/notifications.py

Line 187 in e047607

def block_initialization(self) -> None:

which does not allow to insert MSTeams webhook urls and raise an pydantic validation error

pydantic_core._pydantic_core.ValidationError: 1 validation error for MicrosoftTeamsWebhook
  Value error, Invalid Microsoft Teams Workflow URL provided. [type=value_error, input_value={'url': 'https://team-name.we...ge': True, 'wrap': True}, input_type=dict]
    For further information visit https://errors.pydantic.dev/2.10/v/value_error

Looks like the wrong apprise plugin apprise.plugins.workflows import NotifyWorkflows is used instead of from apprise.plugins.msteams import NotifyMSTeams.

Also

prefect/src/prefect/blocks/notifications.py

Line 194 in e047607

NotifyWorkflows.parse_native_url(self.url.get_secret_value()), # pyright: ignore[reportUnknownMemberType] incomplete type hints in apprise

needs to be parse_url instead of parse_native_url

Working example

from apprise.plugins.msteams import NotifyMSTeams

webhook_url = "https://team-name.webhook.office.com/webhookb2/abcdefgf8-2f4b-4eca-8f61-225c83db1967@abcdefg2-5a99-4849-8efc-c9e78d28e57d/IncomingWebhook/291289f63a8abd3593e834af4d79f9fe/a2329f43-0ffb-46ab-948b-c9abdad9d643"

NotifyMSTeams.parse_url(webhook_url)

hi @deweil - i believe this was an intentional change because of impending changes from Microsoft's end. Is it possible you're using the old version of things?

Hi @zzstoatzz after checking the linked issue I can switch to the workflow based approach.
It wasn't clear to me that the "Incoming Webhook" does not work with the Teams block.
