Upload Sharepoint document to Dataverse File field using Power Automate Flow

[rmarquez]

Hi,

I need to create a Flow that reads a Sharepoint List, identifies whether there is an attachment in a record, and upload the attachment(s) to a File field in Dataverse.  I created a Dataverse table for the attachments and am using the File field to hold the attachment.

When I run the flow, I get an error message "Action 'Upload_file_or_image_content' failed".  The flow is setup as follows:

Get Items (Sharepoint)

Initialize Variable - used to hold ID from the Sharepoint record

Set variable - set to ID from Sharepoint record

Get attachments (Sharepoint) - using ID for Id field

Get attachment content (Sharepoint) - using ID for Id field and Id for File Identifier field

Upload file or image content (CDS) - using variable for ID from above for Item ID, Attachment File for Column name, Attachment Content (Sharepoint) for Content field, DisplayName (Sharepoint) for Content name field

When I look at the output from the Upload file or image content step, I see:

"A supported MIME type could not be found that matches the content type of the response. None of the supported type(s) 'application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=false, application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=true, application/json;odata.metadata=minimal;odata.streaming=true, application/json;odata.metadata=minimal;odata.streaming=false;IEEE754Compatible=false, application/json;odata.metadata=minimal;odata.streaming=false;IEEE754Compatible=true, application/json;odata.metadata=minimal;odata.streaming=false, application/json;odata.metadata=minimal;IEEE754Compatible=false, application/json;odata.metadata=minimal;IEEE754Compatible=true, application/json;odata.metadata=minimal, application/json;odata.metadata=full;odata.streaming=true;IEEE754Compatible=false, application/json;odata.metadata=full;odata.streaming=true;IEEE754Compatible=true, application/json;odata.metadata=full;odata.streaming=true, application/json;odata.metadata=full;odata.streaming=false;IEEE754Compatible=false, application/json;odata.metadata=full;odata.streaming=false;IEEE754Compatib...' matches the content type 'application/octet-stream'."}}}

Any ideas or questions?

Thanks

Can you please share screenshot of how you are saving the file in data verse?

[rmarquez]

Hi Mira,

Thanks for responding.  See the image below.  I should note that I recently added in the Get file content step.  Prior to adding that step, I used Attachment content from the Get attachment content step.  Neither of the values from either step work.

Thanks

Hi Mira,

Please use this screenshot instead.  I didn't catch the top of the Flow in my first screenshot.

Hi Mira,

One more thing.  I created a Flow that reads an Outlook Inbox and uploads attachments into the same table I am trying to load the attachment from Sharepoint.  The Flow using Outlook as a source actually works.  I noticed that this flow uses content bytes in the Content field of the Upload file or image content step.  The code for the Outlook Attachment Content looks like:

 "fileImageFieldName": "crd93_attachmentfile",

            "item": "@items('Apply_to_each_2')?['contentBytes']",

The Sharepoint File Content field is not using content bytes.  Think that may be the issue?  If so, how do I get content bytes from Sharepoint attachments?

Thanks

You need to pass the content as below:

1. In a compose data operation step construct the content in the below JSON format:

{
"$content-type": "image/png",

"$content":base64string

}

Make sure you pass the correct mime type above in content type

Then pass the outputs of this compose data operation to the Upload Image or file as below:

Hi Mira,

I won't know what the file type is.  Since I'm not versant in JSON, do you know if there is a way to handle any file type with JSON?  Or, must I know the file type before going into the Compose step?  If so, does the method for determining the file type require JSON, or is there another way to do that?

Thanks

Hi Mira,

I think I figured out how to dynamically determine the content type.  However, I'm getting the error message below on the Parse JSON step.

BadRequest. The property 'content' must be of type JSON in the 'ParseJson' action inputs, but was of type 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'.

No matter what I choose for Content field of Parse JSON, I get that error message.  From Get attachment content (Sharepoint), I've tried:

Attachment Content

Item

body

I even tried File Content from a Get file content step.  Any suggestions?

Thanks

Hi,

It seems I lost assistance.  I'm still not able to get the right file type to use in the Content field of Upload file or image.  Tried using Compose step as Mira suggested but wasn't successful.  Can anyone assist?

Thanks

[rmarquez]

Hi,

More info:

The output from Get attachment and Get file content shows:

{

  "$content-type": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",

  "$content": "long string of characters"

}

When I use the Compose step as Mira recommended, I get duplicates of the $content-type and $content fields, and the output isn't valid in the Upload file or image step.

Thanks

@rmarquez

Can u please share the compose data operation from ur history run as well as how u pass it to the CDS.

Hi Mira,

Thanks for jumping back in to help.  See the images below.

@rmarquez

Cann u move the upload file or image directly after the compose data operation.. I am not sure why it is inside another apply to each loop.

[rmarquez]

Hi Mira,

I moved Upload file or image directly under Compose data, but I'm still getting the error that basically says it can't recognize the mime type:

"body":{"error":{"code":"0x0","message":"A supported MIME type could not be found that matches the content type of the response. None of the supported type(s) 'application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=false, application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=true, application/json;odata.metadata=minimal;odata.streaming=true, application/json;odata.metadata=minimal;odata.streaming=false;IEEE754Compatible=false, application/json;odata.metadata=minimal;odata.streaming=false;IEEE754Compatible=true, application/json;odata.metadata=minimal;odata.streaming=false, application/json;odata.metadata=minimal;IEEE754Compatible=false, application/json;odata.metadata=minimal;IEEE754Compatible=true, application/json;odata.metadata=minimal, application/json;odata.metadata=full;odata.streaming=true;IEEE754Compatible=false, application/json;odata.metadata=full;odata.streaming=true;IEEE754Compatible=true, application/json;odata.metadata=full;odata.streaming=true, application/json;odata.metadata=full;odata.streaming=false;IEEE754Compatible=false, application/json;odata.metadata=full;odata.streaming=false;IEEE754Compatib...' matches the content type 'application/octet-stream'."}}}

Do you think the problem is with the the content type?: 

"$content-type": "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",

Thanks

[rmarquez]

Hi Mira,

I think I made progress on eliminating the duplicate content-type and content items.  See the image below for the configuration.

This is the input and output from above:

Below is how it comes into Upload file or image content.  It's still not working and the error message is still tied to it not recognizing the mime type.

Any suggestions?

Thanks

@rmarquez 

What is the type of file you are trying to attach?

[rmarquez]

Hi Mira,

In the test case, it's an Excel spreadsheet.  In production, it can be any common file type e.g., PDF, text, image, Microsoft documents, etc.

Any resolution?

I'm also running into this error. The content appears to be in the correct format.
