Hi,

I am creating a word doc to store in Sharepoint of a completed electronic approval. However when I try and extract the approvers ID from the approval, putting the data into a data operation, it takes the approval date but errors when I add the Approvers Name.

The error seems to make no sense to me.

Hi @CW-18021830-0
You’re hitting a type mismatch.

Approval date is a single value. Approver name is not. In Approvals, the “Approvers name” comes back inside the Responses array, and each response is an object. When you drop that straight into a Data Operation or a Word field, the designer tries to treat an array or object as text, and you get the 400 save/runtime error.

Do this instead.

Inspect what you really get

Add a Compose right after Start and wait for an approval
Expression:body('Start_and_wait_for_an_approval')
Run once, open the run history, expand outputs, find:body → responses (array)Each item has responder info (displayName, email, id)

If you have one approver and want the single name

Compose “Approver Name”
Expression (adjust the action name if yours differs):first(body('Start_and_wait_for_an_approval')?['responses'])?['responder']?['displayName']

If you have multiple approvers and want all namesOption A (cleanest, no loops):

Add Data Operation: Select
- From:body('Start_and_wait_for_an_approval')?['responses']
- Map:Name = item()?['responder']?['displayName']
Add Compose “Approver Names (text)”
- Expression:join(body('Select'), '; ')

Option B (loop):

Initialize variable (String) ApproverNames = empty
Apply to each:body('Start_and_wait_for_an_approval')?['responses']
Append to string variable:concat(items('Apply_to_each')?['responder']?['displayName'], '; ')

Use the Compose output everywhereUse the output of your “Approver Name(s)” compose when:
