Posted on by carolynyau

Hi.

I was working on setting up the workflow to automatically reassign approvals to another manager whenever a form submission is initially routed to Person A.

The flow created is as per below. however there is error saying "The request failed. Error code: 'InvalidApprovalRequestor'. Error Message: 'The approval requestor must be a single, valid user account within your organization.'.

Can please help?

The error occurs because the Approvals action requires a single valid user account, but your flow is likely passing multiple users, an invalid value, or a non-email identifier.

The best approach is to determine the correct approver (Person B instead of Person A) before creating the approval by using conditional logic or a variable, and then pass only a single valid email address to the Assigned To field.

This avoids the need for reassignment and ensures the flow runs without errors.

Even though you entered a single email in the “Assigned To” field, the error occurs because Power Automate is likely receiving the value as an object, array, or null instead of a plain string email address.

This commonly happens when the value comes from sources like SharePoint Person fields or Forms responses.

To fix it, ensure you extract and pass only the email property (e.g., Approver.Email or first(...).Email) so that the Assigned To field contains exactly one valid user email string.

@carolynyau

Can you try storing the manager's email in a variable and check the variable in the condition to ensure there are no spaces too

The flow calls Get manager (V2) on the form responder ShiQi Cheeh.

That action returns Chongjin Teoh's email as the manager value. The condition then compares Chongjin Teoh's email against ShiQi Cheeh's email.

You are comparing two completely different people's emails against each other, so the result is always false and the True branch never fires

Try this flow

When a new response is submitted

Get response details

Get user profile (V2)

Create item

Get items

Get manager (V2)

Initialize Variable – ApproverEmail = outputs('Get_manager_(V2)')?['body/mail']

Condition: Responders Email == ShiQi.Cheeh@assaabloy.com
TRUE → Start and wait for approval (Assigned To: variables('ApproverEmail'))
FALSE → Start and wait for approval (Assigned To: original approver logic)
