Duplicate Data, Flow execution repeated with Power automate

Posted on by absolut33

Hi,

I have a flow that receives data from a Microsoft Teams channel, parses it, and adds it to a Power BI streaming dataset. I've noticed that it occasionally duplicates the data.
I've checked the Power Automate logs and I see two logs at that specific time.
Can anyone help me fix this?

Thanks

Hi @absolut33

Silly question but when you look at the trigger is it the same exact value coming in?

Is there any chance the user posting double posted or maybe they noticed latency when posting in Teams?

It is possible you may need to put a check in to verify if its a duplicate trigger, but if you can share the outputs of the flow runs that are duplicates it would help. I do see you showing 2 close together, but need to see the actual trigger JSON to figure out why it triggered twice.

The value is the same. Value comes from an email that I send to the channel (webhook). I've checked that the mail only sent one time.

What json do you need to check, of what step?

Thanks

Hi,

The issue might be caused by the flow triggering twice due to the same data being posted or a latency issue. To fix this, check the trigger values in Power Automate to ensure they're not identical, which could cause duplicate runs.

You can also add a condition to verify if the data is already in Power BI before adding it again. Implement a unique identifier or timestamp to prevent duplicates. Sharing the trigger JSON outputs can help identify the exact cause of the duplicate triggers.

I note that the 2 executions at the same time have the same messageid of teams:

Why does that happen?
