Azure DevOps - email with Attachments

(1) Share

Report

Posted on by alexandrama

Hello,

I'm building a flow that will create tickets in Azure DevOps based on the content of the received email and experiencing an issue with email attachments when attempting to add them to tickets. Although the files are successfully attached to the tickets, they are marked as corrupted and cannot be opened. This problem affects various types of attachments, and users are unable to access the content of these files.

Has anyone faced a similar issue?

Thanks!

Hi,

If my understanding is correct, the ‘attachment content’ is of the byte data type. You have the option to either modify your request to use the byte data type or convert the attachment to Base64 by using base64().

base64(body('Get_Attachment_(V2)')?['contentBytes'])

Let me know if that works.

Anthony.

Hi

Created a video based on this a while ago.

Power Automate - Create Azure DevOps WorkItem and Attachments (youtube.com)

Change the version from 6.0 to 5.0

/_apis/wit/attachments?filename=@{items('Apply_to_each')?['name']}&api-version=5.1

Then under the body use expression
binary('here map the email attachment content bytes')
Set the Body is Base64 to Yes

Let me know how it goes.

Thanks

I followed this video recently and it worked for me: https://youtu.be/Ivdj6Gf_K-M?si=-jUCipPksqBw7kLj. Note, you do need to follow it exactly, including the portions to generate a failed flow. Note, for what I did was to get the attachments from a MS Form submission, and I had to slightly modify the process. But since you are getting the attachments from e-mail, you should be all set since that is what is used in the demo. As abm abm noted, I used version 5.0 of the API as well to get it to work.

I think abm abm is the author of the above video. If so, thank you so much for creating it! It is odd that you need a failure of the flow to get this to work. So many people would have just given up.

Hi

I tried with version 6.0 and worked as expected. Here are the steps:

Action Step: Send an HTTP request to Azure DEVOPS

POST

/_apis/wit/attachments?filename=@{items('Apply_to_each')?['name']}&api-version=6.0

Content-Type

application/octent-stream

Action Step: Send an HTTP request to Azure DEVOPS2

PATCH

/_apis/wit/workitems/@{outputs('Create_a_work_item')?['body/id']}/?api-version=6.0

Content-Type

application/json-patch+json

[
{
'op': 'add',
'path': '/relations/-',
'value': {
'rel': 'AttachedFile',
'url': '@{body('Parse_JSON')?['url']}',
'attributes': {
'comment': 'Bug details',
'name':'@{items('Apply_to_each')?['name']}'
}
}
}
]

Here is my video which is using version 5.1
