I try to create a Pull Request by the Azure DevOps Services REST API. I am using PAT which is working with getting WorkItems like:

#!/bin/bash
source ~/bin/variables.sh
id=${1}
url="$(organization)/$(project)/_apis/wit/workitems/${id}?api-version=7.1-preview.3"
workItem=$(curl -s -u $(presenter):$(PAT) -X GET "${url}")

• organization is our organization-url.
• project is the project name.
• presenter is the user.name (from az account show)
• PAT is the personal access token.

I created a Json like:

{
     "sourceRefName": "refs/heads/U1367_My_Source_Branch",
     "targetRefName": "refs/heads/F231_My_Target_Branch",
     "title": "F231 Source bla foo. U1367 Target bla foo",
     "description": "Bla foo WorkItem: #2117",
     "isDraft": true
}

The Json is generated without newlines:

json='{"sourceRefName":"'${source}'","targetRefName":"'${target}'","title":"'${title}'","description":"'${description}'","isDraft":true}'

and send it with the following:

 url="https://dev.azure.com/$(organizationName)/$(project)/_apis/git/repositories/${repo}/pullrequests?supportsIterations=true&api-version=7.1-preview.1"
 response=$(curl -s -u $(presenter):$(PAT) -X POST -H "Content-Type: application/json" -d '${json}' "${url}")

• organizationName is our organization name 🙂
• repo is the id (Guid) of the repo

I get this response:

{
    "$id": "1",
    "innerException": null,
    "message": "TF400898: An Internal Error Occurred. Activity Id: 169c9863-5441-40a6-8e8d-4c826faf8308.",
    "typeName": "Newtonsoft.Json.JsonReaderException, Newtonsoft.Json",
    "typeKey": "JsonReaderException",
    "errorCode": 0,
    "eventId": 0
}

I checked the permissions of the PAT. I have the permission to create pull requests.

Any suggestions to create a working pull request via the API by a shell script?
