Teams - Create a chat action error: Exception has been thrown by the target of an invocation.

Hi everyone,

 

i'm having a huge problem with a flow, the one you see in the image:

When I add a member (using a variable or writing the email address) and start the flow it always gives me this error in the Create a chat action:

Anyone know how to fix?

 

Thank you so much!!

Hi @Marty3012,
Out of scope request: I am trying to do this exactly "I have a Flow that pulls in a Column of Email Addresses from a Share Point List and then, using a Compose action, creates a long string of the email addresses separated by a semi-colon. "
Would you mind explaining in details how you managed to seperate the email addresses by a semi-colon please?

Thank you!

Hi Capp,

 

Apologies for the delay. Below I have taken the section of my Flow that helps create the list of email

addresses separated by a semi-colon. List of steps;

  • Get items from SharePoint List (no filtering etc, just grabbing the list)
  • Create 'Apply to Each' and loop through the SPL.
  • Put an 'Append to Array' variable in the loop and store the email addresses from the relevant column  e.g - items('Apply_to_each_-_Loop_through_Approvers_Emails_2')?['EmailAddress']?['Email']". Its important to note in this example my SharePoint List has a column called 'EmailAddress' which is of type 'Person or Group'. The code mentioned above refers to the column and its attribute 'Email' e.g '['EmailAddress']?['Email']'. I think this is where a lot of users get stuck with (I certainly did)
  • You can then create a Compose Action outside the loop and store all the email addresses separated by semi colon by using the following code - join(variables('VariableName'), ';')

Hi @Marty3012,

Thank you for taking the time to detail your answer!

I get the same message than others in this topic, it works when I try with an UPN that I write myself but the "Get user Profile V2" action somehow does not manage, from the email address, to retrieve the UPN of my list of users in Excel.

 

So, it's another problem now ahah

When I was getting the 'Exception has been thrown by the target of an invocation' error I found it was triggered for a few reasons;

  • Duplicate emails in the list of emails stored in the Compose action. Once I removed the duplicates I got it working again as Teams doesn't seem to like them.
  • When Power Automate creates a Chat, there is an arbitrary limit of 20 users who can be included in the Chat. Could this also be a reason?

One of the reasons I moved away from Excel to SharePoint lists was because I got a lot of formatting issues. 'Get user Profile V2' seemed to handle emails better from SP.

Hi @Marty3012,

- No duplicate emails;

- I am doing the testing with only two emails;

- And none of them are mine.

I tried with SPL and I get the same error. I guess the explanation is from a previous reply:

"Our issue was the "Members to add" input needed to be the User Principal Name (UPN) instead of their email address. In our organization they are different. We used the "Get User Profile (V2)" action to retrieve the UPN and used that output to create the chat in the 'Members to add' input."

So I need to find a way to make this action Get User Profile (V2) works to get the members UPN but I am not getting any output.
