Mentioning many users in Teams' Channel with "post message v3" causes "internal server error"

Hello everyone,

I have few rather simplistic flows, that post a small message in a Channel on a certain condition. The flows work perfectly well, and I wanted to mention the channel in the posts, only to find out that this functionality is unavailable (yet). And since the members of the channel are not that much, I simply thought of mentioning all of them instead.

Unfortunately, once the post mentions more than certain number of people (or characters I imagine), it simply times out and the status of the calls is "InternalServerError". I am yet to narrow down how many names (or how many characters) cause this hang to happen, but I know the post worked with mentioning 5 names. Then I added 15 more and it hanged 🙂

Any ideas if this is something that I can fix or workaround? I will see if I can split the mentioning into 3-4 separate lines but I have the feeling it will not work. the other idea is to post a message, then post the mentions as few replies below it. however I am not sure how to do that.

Or if this is a bug, I will be relieved to hear it will be fixed soon 😄

Anyway - any ideas are appreciated.
