Package Publishing Step Fails for .NET 8 Azure Functions App

Question

I have a .Net 8 Project running in an Azure Function App and I am using via Azure devops pipeline as CICD. Everything runs fine without issue. Now I amhaving some problems, I have not make a code change, I am only adding a postman test to be included via Azure devops pipeline. However the pipeline jobs fails on publishing package step. Before ever getting to postman testing, so I know for sure, it has nothing to do with my change.

Here is the error:

```bash
Publish Package

##[error]Error: The process '/opt/hostedtoolcache/dotnet/dotnet' failed with exit code 1
##[warning].NET 5 has some compatibility issues with older Nuget versions(<=5.7), so if you are using an older Nuget version(and not dotnet cli) to restore, then the dotnet cli commands (e.g. dotnet build) which rely on such restored packages might fail. To mitigate such error, you can either: (1) - Use dotnet cli to restore, (2) - Use Nuget version 5.8 to restore, (3) - Use global.json using an older sdk version(<=3) to build
Info: Azure Pipelines hosted agents have been updated and now contain .Net 5.x SDK/Runtime along with the older .Net Core version which are currently lts. Unless you have locked down a SDK version for your project(s), 5.x SDK might be picked up which might have breaking behavior as compared to previous versions. You can learn more about the breaking changes here: https://docs.microsoft.com/en-us/dotnet/core/tools/ and https://docs.microsoft.com/en-us/dotnet/core/compatibility/ .

Here is the pipeline task it fails on:

        modifyOutputPath: false

Any pointers to what might be wrong will be helpful.

Hello,
It seems the version for postmanTest package is not good.
You can read in the error message as follows :

Invalid NuGet version string: '1.0.1-DEVS-101_PostmanTest'

So the change is related to your changes with postman apparently.

Hope this helps,
Dimitri.
