.NET Core XUnit Test Azure Dev Ops, Package Issues - .net-core

Question

I have a .NET Core 2.2 Unit Test Setup in an Azure Dev Ops build pipeline, these are xunit tests
steps:
- task: DotNetCoreCLI#2
displayName: 'Unit Test'
inputs:
command: test
projects: '**/Wintegrate.[Tt]est*/*.csproj'
arguments: '--configuration $(buildConfiguration) '
timeoutInMinutes: 5
They are failing for a couple of reasons
Failed Wintegrate.Tests.BoomiRestClientTests.GetDeployedPackages
Error Message:
Assert.Equal() Failure
Expected: OK
Actual: 0
and
Failed Wintegrate.Tests.BoomiServiceTests.GetAtomsAndMolecules
Error Message:
Newtonsoft.Json.JsonReaderException : Error reading JObject from
JsonReader. Path '', line 0, position 0.
Stack Trace:
at Newtonsoft.Json.Linq.JObject.Load(JsonReader reader, JsonLoadSettings
settings)
at Newtonsoft.Json.Linq.JObject.Parse(String json, JsonLoadSettings
settings)
at Wintegrate.Domain.BoomiService.GetAtomsAndMolecules() in
d:\a\1\s\Wintegrate.Domain\BoomiService.cs:line 37
at Wintegrate.Tests.BoomiServiceTests.GetAtomsAndMolecules() in
d:\a\1\s\Wintegrate.Tests\BoomiServiceTests.cs:line 53
The tests work fine when running locally from Visual Studio

According to the error message:
Failed Wintegrate.Tests.BoomiServiceTests.GetAtomsAndMolecules Error
Message: Newtonsoft.Json.JsonReaderException : Error reading JObject
from JsonReader. Path '', line 0, position 0. Stack Trace:
This error should not come from the Azure Devops tool or your build definition. It is more related to the project or the environment settings.
So, please try to run the test on the your agent server directly, and check if still have the same issue.
Hope this helps.
