Unable to parse base64

(0) ShareShare

Posted on by 2
Hello everyone,
 
I wanted to create a flow which automatically creates an Azure DevOps work item for each mail I get via Outlook. File attachments are to be included in the work item.
 
I followed the instructions of https://www.youtube.com/watch?v=Ivdj6Gf_K-M, which include:
1. When a new email arrives
2. Create Work Item
3. Send HTTP request to Azure DevOps (to upload the image in Azure DevOps)
4. Parse JSON
5. Send HTTP request to Azure DevOps (to link the image to the correct work item).
 
When I test the flow within Power Automate, everything works smoothly, the ticket is created and the file attached. When I run a test outside of Power Automate (i.e. I send an email), the flow does not work and I get this error message:
 
Now this problem has been mentioned several times, there is even a solution in the description of the YouTube video. But none of this works for me. I checked the image code, tried messing around with it, tried different api versions, nothing helps.
 
What really gets me is that the flow test in Power Automate just works fine, so somehow Power Automate is able to parse the base64 encoded bytes.
 
Does anyone have any idea how to solve this? Any help is appreciated!

    Please explain what you mean saying "run a test outside of Power Automate"?

    a manual test, i.e. I send an email with an attachment to my mail account, from which Power Automate creates an Azure DevOps work item.
