Is there any way we can get task name in the release pipeline to execute specific task based on an condition - azure-devops

Question

I'm working on a release pipeline there are around 3 task in the 1 Agent. taskA,taskB,taskC
I want to run specific task based on specific task failed. I tried custom condition but it didn't satisfied my case.
I want task C to be execute when only task B is failed for that I'm using output variable as well. In this case its working only for taskB. When TaskA failed Task B will skip and output variable become null in that case my task C is execute which is not correct.
I'm trying to make a condition which fulfill both TaskA and TaskB condition.
if TaskA failed --> TaskC should not run
if TaskB failed --> TaskC should run.
Here is my condition:-> and(eq(Agent.JobStatus, 'failed'), in(variables['oneboxout.oneboxvar'],'False'))
Is there any way we can get task name only so my work would be easier.
Below are my task screenshot for your reference.

The answer is yes.
We could use the REST API Releases - Get Release to get the task name or status；
https://learn.microsoft.com/en-us/rest/api/azure/devops/release/releases/get%20release?view=azure-devops-rest-6.0
As the above REST API, we need provide the current release Id to that REST API. To resolve this, we could use the REST API Releases - List with Parameter definitionId={definitionId} and powershell parameter Select-Object -first 1 to get the current release Id.
To resolve this request, I would like use following method:
Summary:
Add powershell a task (Let's call it Get JobB task result)between JobB and JobC to invoke REST API
to get the result of the JobB with condition Even if a previous task has failed, unless the build was canceled.
Set a variable RunJobC with different value based on the result of the task JobB in above powershell task.
Set condition and(always(), eq(variables['RunJobC'], 'True')) for the JobC.
My test scripts (Check Allow scripts to access the OAuth token option in the Phase):
$url = "https://vsrm.dev.azure.com/M<YourOrganization>/<YourProject>/_apis/release/releases?definitionId=24&api-version=6.0"
$RealeasePipeline= Invoke-RestMethod -Uri $url -Headers #{
Authorization = "Bearer $env:SYSTEM_ACCESSTOKEN"
} -Method Get
$ReleaseId= $RealeasePipeline.value.id | Select-Object -first 1
Write-Host The current Release Id: $ReleaseId
$url2 = "https://vsrm.dev.azure.com/<YourOrganization>/<YourProject>/_apis/release/releases/$($ReleaseId)?api-version=6.0"
$ReleaseInfo= Invoke-RestMethod -Uri $url2 -Headers #{
Authorization = "Bearer $env:SYSTEM_ACCESSTOKEN"
} -Method Get
$TargetTask=$ReleaseInfo.environments.deploySteps.releaseDeployPhases.deploymentJobs.tasks| where { $_.Name -eq "JobB"}
Write-Host JobB task Result is: $TargetTask.status
if ($TargetTask.status -eq "succeeded"){
Write-Host ("##vso[task.setvariable variable=RunJobC]False")
}elseif($TargetTask.status -eq "Failed"){
Write-Host ("##vso[task.setvariable variable=RunJobC]True")
}
My test result:
