Hi, I am getting this error now on my OnSelect of a submit button, which literally popped out of nowhere. I didn't make any modifications to anything.

Office365.SendEmailV2 failed: { "status:" 400, "message": No input parameters provided. Please provide required input parameters 'To', 'Subject' and 'Body'.\r\nclientRequestId:8d74306b-de41-44aa-ac0f-a6b93be9760a", "error": {"message": No input parameters provided. Please provide required input parameters 'To', 'Subject' and 'Body'."}, "source": 01.p.azurewebsites.net"}

I couldn't find a solution anywhere. The error in the OnSelect is in this function:

Office365.SendEmailV2(
hidden_queued_managers,
"A New Problem Has Been Submitted to " & Dropdown_Process.Selected.Process & " Team. Please Assign a Problem Lead.",
"A new problem has been submitted to the " & "" & Dropdown_Process.Selected.Process & "" & " team in the " & "" & Dropdown_OwnerGroup.Selected.Result & "" & " Group. Please click the link below to navigate to the Admin Tool to assign a Lead to begin investigating this Sherlock." & " " & " " & "
You can process the problem and assign a Lead by clicking the following link:" & " " & " " & "insert link here",
{
Importance: "High",
Cc: hidden_queued_process_leads,
IsHtml: true
}
)

This was working completely fine until this week. I looked at the label I'm using for my To in the email:

hidden_queued_managers =

Match(Concat(Filter('Cascading Dropdown (Do Not Remove)',Dropdown_Process.SelectedText.Process in Process And Dropdown_OwnerGroup.SelectedText.Value in 'Owner Group'),Manager.Email&", "),"^(?<trim>.*), $").trim

I noticed it's telling me:

Dropdown_OwnerGroup = PowerApps encountered an internal error trying to evaluate this expression. | Data type: Control

Any help would be very, very appreciated!

Hi @ninos-shiba

Just to clarify, hidden_queued_managers is a label on your screen? I think you need to need to reference the Text property in your call to SendEmailV2 like so:

Office365.SendEmailV2( hidden_queued_managers.Text, "A New Problem Has Been Submitted to "......

Correct, it is a label on my screen that is invisible (visible = false). It was working before though. 😞 Should I change it then?

Hi @ninos-shiba

Yes, I would change that to see if that helps.

You could also make the label visible whilst you're diagnosing this, to confirm that the label is producing a valid and correct 'to' value.

The label appears normal, i.e., it's a string and looks like this:
"firstname.lastname@company.com"

Have you tried to add the word Outlook to the call? You have:

Office365.SendEmailV2(hidden_queued_managers.....);

I just tried with this and it worked for me. (I changed the emails and such to post here.)
Office365Outlook.SendEmailV2("someone@email.com", "this is the subject", "this is the body", {From: User().Email, Cc: "another@email.com", Importance: "high"})

Ive never used Office365.SendEmailV2, I've always used Office365Outlook.SendEmailV2. Not sure if you use outlook but if so that might fix it. Good luck!
