Start and Wait for Approval with Attachments

Posted on by imranzafar

Hi, I have this flow where I am filtering attachments of type ".pdf" from sharepoint list and want to send these as Attachments with "Start and Wait for Approval" action. However, it is giving error:

The request failed. Error code: 'InvalidRequestContent'. Error Message: 'The request content was invalid and could not be deserialized: 'Could not find member 'ContentBytes' on object of type 'ApprovalsConnectorFileAttachment'. Path 'attachments[0].ContentBytes', line 1, position 308.'.'.

I am using a variable and through this I can send filtered attachments in email but somehow "Start and Wait for Approval" is giving error. Need help with this.

Regards,

Imran

You may need to wrap the Name and Content in quotations "" as they need to be strings.

They are in quotes. Please note that I am using same Array variable to send email attachments successfully but somehow it is not working in case of Approval action.

I mean the variables also need quotations, like:
"Name" : "DisplayName",
"ContentBytes" : "This variable also"

BadRequest. The request failed. Error code: 'InvalidRequestContent'. Error Message: 'The request content was invalid and could not be deserialized: 'Could not find member 'ContentBytes' on object of type 'ApprovalsConnectorFileAttachment'. Path 'attachments[0].ContentBytes', line 1, position 560.'.'.

Hi Jdoss,

This link helped and issue is resolved.

The main issue (for future reference for other users) was that:

1. "Start and wait for Approval" needs "Content" in JSON of Append to Array Variable. Like:
{
"Name": @{item()?['DisplayName']},
"Content": @{outputs('Get_attachment_content_2')?['body']}
}

2. For Send an Email (V2), we need to include "Contentbytes". Like:
{
"Name": @{items('Apply_to_each')?['DisplayName']},
"ContentBytes": @{body('Get_attachment_content')}
}

Thank you for your help.
And I hope above points that I have mentioned will help others who may face similar issue in future.

Regards,
Imran
