Current Iteration Query Script Devops Looping Through Projects - azure

Question

I'm trying to put a script together that will let me loop through projects and create queries relevant to the current iteration.
I can loop through and create queries until it comes to looking at the iteration path and then it doesn't seem to like it.
When I run my script all of the other queries are created, and this one is as well, but it brings up an error when I go to look at it because it's posting that it's not in the right form. How can I get this query to loop through like the others and bring back the appropriate team in the process?
I'm assuming that somehow I've got to put project and team as variables? I tried $project as well but that just presented a similar error. Although I'm also confused about about the "" since the code doesn't like that either, and it won't even create the query when I've tried that.
$JSON27 = #'
{
"name": "Current Sprint Query", "wiql": "SELECT [System.Id], [System.WorkItemType], [System.Title], [System.AssignedTo], [System.State],[System.Tags],[Microsoft.VSTS.Scheduling.OriginalEstimate],[Microsoft.VSTS.Scheduling.CompletedWork],[System.IterationPath] FROM workitems WHERE [System.TeamProject] = #project AND [System.WorkItemType] <> '' AND [System.State] = 'Closed' AND [System.IterationPath] = #CurrentIteration('[Project]/Team') ORDER BY [System.WorkItemType]"
}
'#
$response27 = Invoke-RestMethod -Uri $url1 -Headers #{Authorization = "Basic $token"} -Method Post -Body $JSON27 -ContentType application/json

Answer 1

Please refer to the following script to get the project name first, and then create a query by looping through the obtained project name.
Please use #CurrentIteration('[Project]\\Team') instead of #CurrentIteration('[Project]/Team') or #CurrentIteration('[Project]\Team')
$token = "your PAT"
$url="https://dev.azure.com/org name/_apis/projects?api-version=6.0"
$token = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes(":$($token)"))
$response = Invoke-RestMethod -Uri $url -Headers #{Authorization = "Basic $token"} -Method Get -ContentType application/json
echo $url
foreach ($project in $response.value.name){
$url3="https://dev.azure.com/org name/$($project)/_apis/wit/queries/My Queries?api-version=6.1-preview.2"
echo $url1
$body = "{
`"name`": `"query name`",
`"wiql`": `"Select [System.Id], [System.State] From WorkItems where [System.IterationPath] = #CurrentIteration('[$project]\\$project Team') `"
}"
echo $body
$response3 = Invoke-RestMethod -Uri $url3 -Headers #{Authorization = "Basic $token"} -Method Post -Body $body -ContentType application/json
echo $response3
}

Summarizing the discussion in comments as an answer below:
So, as the error message calls out, I think the issue is that you have #CurrentIteration('[Project]/Team') in your query instead of #CurrentIteration('[Project]\Team').
Your query should be this instead:
$JSON27 = #'
{
"name": "Current Sprint Query", "wiql": "SELECT [System.Id], [System.WorkItemType], [System.Title], [System.AssignedTo], [System.State],[System.Tags],[Microsoft.VSTS.Scheduling.OriginalEstimate],[Microsoft.VSTS.Scheduling.CompletedWork],[System.IterationPath] FROM workitems WHERE [System.TeamProject] = #project AND [System.WorkItemType] <> '' AND [System.State] = 'Closed' AND [System.IterationPath] = #CurrentIteration('[Project]\Team') ORDER BY [System.WorkItemType]"
}
'#
EDIT:
By default, shared queries and new queries are scoped to the current project. For querying across multiple projects, you can add the TeamProject field to filter to a select number of projects as:
..
AND [System.TeamProject] IN ('Project 1', 'Project 2', 'Project 3')
However, using the #CurrentIteration macro would need you to select a Team and may not work across Projects and Teams. Check this idea on Developer Community for more details.
