Adding the attachments to Azure DevOps work item in "Create a Work item" step

Hi ,


Is there a way to attach a certain file from email directly to the attachments section in the User story of Azure DevOps, I'm currently having a flow that creates a work item whenever tehre is a new email but can't able to process the attachments linked to it. I need those attachments in the user story itself. Can somebody help me??

Hello @gyegan ,

I see the issue is with the url that you are passing in the body of the request. That should be the output of the compose you get for building the url. Ideally the compose should be “outputs(‘Compose_2’)[‘url’]. The url in the the request body should be the output of this compose step. Please let me know if you need any additional info.

Thanks for the quick response!  So the output is actually the URL I can verify  the error details.  I have attached some screen shots too.

“path”: “/relations/“,


please try this in the body where it’s “/Relations/“

No luck, i'm at my wits end!  I have created several times, made sure the msflow user is a user in AzureDevOps, tried different file types.   Is there a way to see if the file really posted?

Updated it so the run body was:


“path”: “/relations/“,
"comment":"Adding attachments"

If you follow your url in patch call you should be able to see and open the file uploaded in Dev Ops: 

In your case:


I would assume it is uploading, otherwise you'd get a failure earlier in the process.  That leaves the an error in your patch call where you are associating the file you just uploaded to the work item.  Your error message references a valid patch document in the body.


At which point I'd assume your body has an issue.  And in looking at your screen shot it looks like you are using  smart quotation marks “ instead of quotation marks " and for path and relations.


for reference this is what my body looks like on a process that's been running for weeks.


    "op": "add",
    "path": "/relations/-",
    "value":  {
       "rel": "AttachedFile",
       "url": " ",
          "comment": "Added via initial email"


See if that helps.

It was the darn quotes! I'm on a mac so that might have something to do with it. Is there a way I can buy you a cup of coffee or tea?  You just saved my sanity!  Thank you!

Thanks a lot for this great guide, it has been very helpful for me. I am getting the following error in the POST action: 

InvalidTemplate. Unable to process template language expressions in action 'Post_Attachment' inputs at line '1' and column '48619': 'The template language function 'binary' was invoked with a parameter that is not valid. The value cannot be converted to the target type.'.


I guess it is something with the binary, though I am using it as you mentioned in the guide:




 Any assistance will be very appreciated.

I have setup the required steps and the attachments are saving to the Work Item however it is not saving the attachment name or extension.


If I download the attachment and add the appropriate extension I can open and view the data.


Anyone have any ideas what I'm missing here and how to pass this information as well?

Hi @TheSwilliam ,


Greetings to you!


I need some assistance regarding the image attachment issue you posted the resolution on.

I have just exactly followed your described ways to fix the broken image attachment problem with Azure DevOps. I mean, the image file comes in work items as corrupted on Azure DevOps.

I followed each and every step of the resolution defined here but still am failed to fetch in-body attachments (images inside the email body) to Azure DevOps work items. This is what I want to achieve below:




This is my flow below:




Flow segmentation below:






Could you please cross-check my flow and identify the trouble caused there?


Any suggestions/hints would mean a lot to me if you could assist.


Thanks & Regards,


I am trying to apply the same solution for attachments. facing an error in "Parse Json".


Is there any constraint related to attachment type? like it should be a text or anything?



Thanks in Advance!

Bansari Pandya.


Can you please share your work around? I also tried to upload excel or pdf. Facing error in Patch Action.


Thanks in Advance!

Bansari Pandya.



Just wants to say thanks! same issue I am facing now it's resolved. 



Bansari Pandya.

Attachments will not show up in the description. They will be in the attachments tab in the work item. I have attached an image for reference. 




@TheSwilliam This helped so much!!!  Thanks for the great detailed steps!!!  Do you know how to get images in the body of the email to show up in the DevOps bug?

Hi @TheSwilliam,


Thanks for this solution. I have implemented the solution but I am unable to see 'url' output function to add to the 'compose 2'. Is it something that I have to manually input some where, if so where I can do that? I tried to edit the function with the following "outputs('Compose')['url']" but no luck. So just used "Outputs" function as below:




But below is the error message I get when the process run:


You must pass a valid patch document in the body of the request.
Azure DevOps ActivityId: d88ec6cb-091d-4a66-8c99-fa19f37ff6bf

clientRequestId: c230e3c1-3387-4d03-b28c-7e5ba9272a09


Any help on this is much appreciated!
