HTML table - error message in 'From' field

(0) ShareShare
ReportReport
Posted on by

Hello,

I'm trying to insert a table into an email as part of an approval flow rejection process but keep experiencing the following error:
The 'from' property value in the 'select' action inputs is of type 'String'. The value must be an array.

I can't find anything like 'Response Value' in the Dynamic Content if that's what I should be doing?

Please see image below. Thanks

    If you just used Start an approval, then you will need to also add a Wait for an approval. If you just had Start an approval, then that's why you're not seeing the Outcome as an option for your condition.

     

    Alternatively, you can use the single action Start and wait for an approval.

    Approval data is stored in a Dataverse table. You can get the outcome of the approval from the Responses Comments field in your approval action. This is an array since approvals can have multiple approvers. You may need to do some manipulation on the array depending on how you want to use the comments.

    @David_MA thanks. 
    Would that approach work in getting the rejection comments fro the approval flow? I'm guessing yes if that data is recorded in the associated SharePoint List?

    @grantjenkins thanks. 
    It's 'Start an approval' and its set up for the first to approve.
    I've tried changing Condition value to Outcome but can't see it as an option. Do I need to create an Expression?

    Does your Approval have one or multiple approvers? And what is the setting on your Approval - all must approve, first must approve, etc.

     

    Also, in your Condition you should be using Outcome is equal to Approve.

    Based on your screen shot, the data in your Select is coming from Microsoft Form responses. Your link is coming from a SharePoint list, which is not part of the output in the From in your Select. You can only choose values from the current Select source.

     

    You will need a separate Select that uses the SharePoint values as the source in order to get the link.
