Hi, Does anybody help me why I can't send approval with attachment.
It works fine without the attachment, but when I try to attach it, the flow freezes for 10 min and gives an error at the end.

"error": {
        "code": 502,
        "source": "flow-apim-europe-002-westeurope-01.azure-apim.net",
        "clientRequestId": "8841d657-6f8b-42c1-b64c-80db7d93e547",
        "message": "BadGateway",
        "innerError": {
            "error": {
                "code": "XrmApiServerError",
                "message": "Request to XRM API failed with server error: 'Message: An error occurred in MoveAttachmentToAzureDataLake: Logic for msdyn_flow_approval entity storage is not

                            implemented\nCode: 0x80040265\nInnerError: '. The tracking Id is '8841d657-6f8b-42c1-b64c-80db7d93e547'."
            }
        }
    }

I really need help with this.

Using flows

Hi,

1) Avoid attachments in the Approval connector

Instead of using the built-in attachment field, host the file elsewhere (e.g., SharePoint) and provide a link in the approval description.

Example:

Upload your file to SharePoint in a known library.
Use Get file content and Create sharing link for a file or folder.
In the Approval Details field, put something like:

Please review this document: [Discount Approval Steps.docx](https://yourtenant.sharepoint.com/sites/...)

This method is fully supported and very reliable.

2) Use adaptive cards for approval

If you absolutely must embed attachments, consider switching to Teams Adaptive Cards approvals, where you can include:

Rich card content
Links
Even thumbnails

This approach requires building the card JSON and sending via Post an adaptive card and wait for response, but avoids the problematic backend entity.

3) Contact Microsoft Support

If your business process requires official attachment support in the Approval connector:

Open a support ticket with Microsoft referencing:

XrmApiServerError in MoveAttachmentToAzureDataLake Entity: msdyn_flow_approval Code: 0x80040265
Ask them to confirm whether your environment supports attachments.
If not, request provisioning or migration guidance.
