I am having the exact same issue with all of my tiggers for these flows as well, haven't been able to find a fix but seems like a big issue right now?

It seems like the 'When keywords are mentioned' action is still broken - or - they changed how it works when using multiple keywords that are separated by a comma.

My flow has worked fine since recently.

I can confirm that it triggers when I edit it to only use one keyword, but as soon as comma's are used to add multiple words, it's a no-go.

Just discovered this was broken today.

Has anyone opened a ticket with Microsoft on this issue? I am going to try.

We had a few perfectly working flows that broke when we updated the solution from our dev to prod. I wasn't even working on those flows, just adding a new one to the solution.

I really needed this to work and did not have time to wait for Microsoft to fix this, so I have a solution.

I consider this more a workaround than a solution, but it works and the trigger response is near instant.

1. Change your trigger from Teams Keywords to 'Teams - When a new messages is added to a chat or channel'

2. Initialize a variable called 'Keywords' or whatever you want, type = array, content = make it a json array of your keywords:
[

"these",

"are",

"my",

"words"

]

3. Action: Teams - Get Message Details:

Message = triggerOutputs()?['body/value']?[0]?['messageId']

Message type = channel

Team = triggerOutputs()?['body/value']?[0]?['teamId']

Channel = triggerOutputs()?['body/value']?[0]?['channelId']

4. Compose (join subject and body words into array):

split(toLower(concat(outputs('Get_message_details')?['body/subject'], ' ', outputs('Get_message_details')?['body/body/plainTextContent'])), ' ')

5. Condition (checks if keywords are present):
left box = length(intersection(variables('Keywords'), outputs('Compose')))

operator = is greater than

right box = 0

So this looks for new messages, inits a variable array of your keywords, creates an array of words from the message subject and body, and compares that against your keyword array. Hope this helps someone.

I was just testing this trigger, and I got the error message "Only single words are supported for this trigger."

I have never used this trigger before. Did it previously allow multiple keywords or phrases?

The document seems to say that you should use "single" keywords separated by a comma: Microsoft Teams - Connectors | Microsoft Learn | When keywords are mentioned. But I could only get the trigger to work when I uses only a single keyword:
