Add attachment using file content

[inoubli nader]

Hi,

I'm trying to add a file via API to an issue. I'm using Microsoft Flow to make my calls and there is no dedicated 'file' value like there is in Postman so everything has to be put into the headers and body. Also the file that I'm uploading does not exist online rather I need to create the file with the file content.

For example here is a call I have tried from Postman:

This results in the following 500 server error:

<message>org.apache.commons.fileupload.FileUploadException: Stream ended unexpectedly</message>

This is how the same call looks in MS Flow:

Please advise

Thanks,
