@CU23070134-0,

MS has retired this connector for More Information https://devblogs.microsoft.com/microsoft365dev/retirement-of-office-365-connectors-within-microsoft-teams/.

You must replace it with one of the new Teams actions Post a message in a chat or channel.

@CU23070134-0,

As @MS.Ragavendar mentioned this is a known issue. Microsoft has retired the Post a message as the Flow bot action.

Old flows using it now show Invalid parameters”and may crash the designer with memory errors.

The fix is to delete the Flow bot action and replace it with supported Teams actions like Post a message in a chat or channel.

Using Edge InPrivate also helps avoid editor out‑of‑memory errors and also sometime 32bit version of the browser will also throw this error try to upgrade to x64 version accordingly (follow the software process as per your organization)

@CU23070134-0,

Open using Edge InPrivate + throttling (only needed)

Open Edge → InPrivate

Close all other tabs

DevTools → Performance tab

Enable CPU throttling

Open flow

Immediately delete Flow bot step

Save

@CU23070134-0,

Save a copy WITHOUT opening the editor .

Go to My flows

Select the flow which is causing the issue

Choose Save as and Give it a new name

DO NOT open it yet and Disable the original flow

Open the copied flow, In many cases, the copied version took long time to open.

Delete the Flow bot action

Save and Re‑enable

This worked for me in on of this kind of issue.

Are you having multiple actions which is being deprecated? If yes there will be challenge while deletion of the actions.

I would suggest you raise a Microsoft Support Ticket regarding the issue - Get Support in Power Platform - Power Platform | Microsoft Learn, A dedicated member from the support will assist on this issue.

By Navigating to the Url https://admin.powerplatform.microsoft.com/support/requests you can raise the support request.

Over the past few days, I have been getting this 'out-of-memory' error on many flows and seeing a long delay before the initial flow validation process has completed. This seems to be new Designer behaviour as I have not seen this before but am now seeing it across most of my flows. It is making the updating of many flows impossible.

I'm seeing the same issues as @biterbit this week. Is there potentially a memory leak in the new designer? I had task manager open on my other screen and watched the memory usage climb as I used it until it crashed. Saving in particular seems to spike memory usage. That on top of very slow validation for any changes to a flow has made the new designer almost unusable for anything beyond small, quick edits.
