Hi There,

I have a flow where I am using a trigger called 'When a new email arrives in a shared mailbox (V2)'. I am performing some actions in between finally I am supposed to send a reply to all having output from those actions in between.

Problem is I am getting an error 'bad request' in Reply to email (V3) action. The error is like this:

"Action 'For_each_2' failed: The execution of template action 'For_each_2' failed: the result of the evaluation of 'foreach' expression '@triggerOutputs()?['body/sensitivityLabelInfo']' is of type 'Null'. The result must be a valid array."

This is how the flow looks:

The error I am getting is like below:

Can someone please help me identify where I am going wrong?

Regards,

Arnab

It seems like the issue is in your Apply To Each action - the value you're using there:

triggerOutputs()?[body/sensitivityLabelInfo]

is not a valid array to run a loop against.

What data item are you trying to iterate through with your loop?

Hi there!

That's strange! You should be able to add this to handle empty labels.

coalesce(triggerOutputs()?['body/sensitivityLabelInfo'], json('[]'))

Hi trice602,

Copilot is also giving me this response (coalesce(triggerOutputs()?['body/sensitivityLabelInfo'], json('[]'))). But how to use it in my flow? I don't have any json or parse json in the flow. Can you please suggest?

Hi Tomac,

My for each is @{outputs('Find_files_in_folder')?['body']}. Basically, for all the files available with matching criteria.

Also, this problem is arising with only 'Reply to email (V3)' action. It works perfect with 'Send an email from a shared mailbox (V2)'

Totally confused now. :(

@AC-23071728-0 Hi,

Your question is really confusing.

The description and the screen shot are not the same...

If the error is from your screen shot, choose 'Original Mailbox Address', and the value should be the shared mailbox address.

Hello stampcoin,

You are right. I've added 2 screen shots. First one, when I was trying with Reply to email v3 where I was getting that error. The second one is when I tried the same flow but with send an email v2 instead reply to an email v3. Second one worked.

It's working now with both the actions. I tried your suggestion to add Original Mailbox Address and it worked like charm this time (I have changed some of the action names). I didn't know it was necessary. Thank you for pointing it out.

Warm Regards

Arnab
