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??

Hi @TheSwilliam @gyegan @Anonymous or anyone else who had luck with this. This looks like an awesome solution and I am really hoping to get this implemented however, I am running into an issue with the second compose action.


My output does not list URL and only output. Any suggestion on how to resolve this? Note - Below is my desired outcome. Thanks in advance!




Were you able to resolve this? I am also unable to see 'url' as an option for 'compose 2'.

@npu_2022 @HerbsterK The 'url' is actually an output function: outputs('Compose')['url'] The outputs function is getting the url property from the response json from Post Attachment. Code snippets for the compose steps: Compose: { "inputs": "@body('Post_Attachment')" } Compose 2 { "inputs": "@outputs('Compose')['url']" }


I've just implemented the flow. Flow isn't showing me the nice 'url' to pick from the Dynamic list, so adding an Expression and just typing in the text as per @TheSwilliam works.  It turned 'pink' after saving/reopening the flow.

Thank you so much. this worked perfectly for me @TheSwilliam 

I am receiving the below error while running the flow, could you please check 

"Unable to process template language expressions in action 'Post_Attachment' inputs at line '0' and column '0': 'The template language function 'binary' was invoked with a parameter that is not valid. The value cannot be converted to the target type.'."






Hello TheSwilliam could you help me, I am trying to create this request for "CHUNKED UPLOAD" but I can't get a return, even if I use the upload type as chunked the activity doesn't return the necessary ID, I can do the flow for the attachments that are smaller but the bigger ones I can't upload. Your example is very similar to the one I did for the smaller file uploads, but I would like to ask for your help to try to verify what I might have done wrong in this step

The documentation says that we should start the upload [POST] and then perform a [PUT] with the ID that the first activity provides, but my flow does not go beyond the PUT activity, the error is related to the size of my file and I need to upload that..




Thanks... going back to a few questions back...

Do you know how to get images in the body of the email to show up in the DevOps bug?




Or its not possible yet?

@TheSwilliam i presume this worked at one point, but now I am getting the same "Unable to process template language expressions in action 'Post_Attachment' inputs at line '0' and column '0': 'The template language function 'binary' was invoked with a parameter that is not valid. The value cannot be converted to the target type" error as @SwathiB et al. Appreciate the detail and effort you put into this. It needs an update.

Here is a screenshot of the outputs of the "Current Item." I don't see the word "ContentBytes" anywhere, presumably that is why the binary (and base64) expressions are failing. Gotta love those updates!

Resolved by creating a control that looks for PDFs, which can be uploaded via HTTP Request to Azure DevOps action. If not PDF, iterates thru the various content types and uploads.



^ The dynamic content in the control is "Attachments Content-Type". Mixed and matched the puzzle pieces from the two resources below.

PDF Attachments - 
@SwathiB fyi this should work for you too

there's nothing special in Compose 4 i was using it to troubleshoot

The PDF attachment link is not to clear, basically do the above procedure, but use base64 expression instead of binary

It was due to a typo and it's working perfectly fine for me after I made the correction.

I corrected my typo error and its working for me now 🙂

Any ideas how I could do something similar, but using http JSON request?  I'm not doing the "create a work item" action so I don't have a dynamic ID I can place in the URL.  Currently, after the "Get Response Details" from MS Form, I have:




Then after this, I tried to add a second one (again I don't have work item ID so I don't know how to do it):




@Anonymous as I understand it, you will need to create a work item to dynamically pass through its ID to upload an attachment to it. hope this helps!

@Anonymous I'd recommend adding all the dynamic responses from a form to the work item's description via create work item, then use the 2 HTTP actions to upload whatever attachments submit

Did anyone has issues opening the attachment after the file was posted on work item.

I am currently unable to view any file using the flow that was posted.


It worked in the past and nothing has been changed since the past year. any leads on that ? @Sucupira @SwathiB @Anonymous @nerfherder
